I'm looking for some honest opinions. I'm going to copy and paste the (re-formatted for easy reading) email chain.
Background: My cousin and I had made plans to do dinner before Christmas, on the 21st. We agreed to a date and place, but not a specific time. I assumed 6:30 or so, which is the time we've met for dinner before. (We've only lived in the same town for less than a year, so there isn't much history in terms of "how we've always done things".) Another important note is that I had invited her on 12/03 to attend a basketball game with myself and DBF. She cancelled two days beforehand, because she found out friends were coming into town and she wanted to see them. These were tickets he got from work, and he got an extra one for her, but it was too late to turn it in for someone else to use, and there was no one else we could ask. Technically she dumped us for a "better offer", but I understood.
This email has taken place over the last day.
Me: "What time are we meeting on Thursday? Iím doing HH with my co-workers @ NearbyBar at 5:30. Do you want to meet me there and then we can go on to dinner? Thursday was the only evening everyone was available. "
Cousin: "I thought we could meet about 6 or so. I would rather not go to NearbyBarÖ "
Me: "Can we make it 6:30? That will give me time for a quick drink w/them and then I can leave there @6:15 and meet you."
Cousin: "I have to leave work @ 5:00, no more overtime allowedÖ. I really donít want to hang out for an hour and a half and donít want to go home either."
Me: "Well, then meet us for happy hour!"
Cousin: "We have had these plans for 4 weeks, time and place agreed to. Canít you skip with your co-workers?"
Me: "Place, yes, but you never specified a time. I assumed 6:30-7 pm, which is a normal after work dinner hour. I assumed I would have time for a quick drink, because usually happy hour comes before dinner, so I figured I could do both. Seriously, why canít you meet us for a drink and then weíll go on to dinner?"
Cousin: "I just donít feel like it. I was looking forward to a nice quiet dinner with youÖ I donít want to be gallivanting all over town."
Me: "Well, we can have a nice quiet dinner, at a normal dinner time. What time were you thinking of eating? 5:30 is way too early. We arenít going to be gallivanting all over town. Itís only Monday, how can you know what you would feel like doing 3 days from now? You need to get out more, for crying out loud. It wonít kill you to have a drink with some new people. Co-workerA and Co-workerB are really nice and you might actually have a good time. "
Cousin: "No, I donít want to eat at 5:30, but if we met at 6, we didnít have to sit down right away. To be honest, I have an interview the next day and I donít want to be all stuffed up and no feeling well from cigarette smoke in a bar and I donít want to stay out late, because this one in particular is really important to me and I want to get a good nightís sleep and so I can really put my best face forward."
Me: "OK, where do you see we are staying out late? I meet you for dinner @ 6:30, dinner is over by 7:30-8:00 at the latest, and you are home by 8:30. The bar will not be all that smoky at 5:30 on a Thursday. But fine, Iíll meet you at RestaurantName at 6 pm and just skip the happy hour. I was just trying to work out both. Whatever."
Cousin: "Maybe we should just reschedule after the holidays."
Me: "If thatís what you want to do, we can. I have to be honest and say that I am really disappointed you canít be flexible here. Asking to meet you at 6:30 would not be that big of a hardship."
Cousin: "It really has nothing to do with my being flexible. Itís about manners. We had plans for a Christmas dinner, we set almost 4 weeks ago. You said ďit was the only night everyone was availableĒ, wellÖyou really werenít available. Was it so difficult for you to say to your co-workers ĒI have plans, but let me consult with my cousin and find out the exact time she was thinking about before I commitĒ. If you had done that I might have been more amenable to meeting you there. Instead, you change everything without consulting me. They were my plans too and a little consideration would have been appreciated. "
Me: "Aha, manners. Like when you agreed to go to the basketball game and cancelled after Boyfriend already said heíd take the tickets? I didnít think anything of that, because I can certainly understand that if friends come into town you want to see them, but if we are playing the whole manners card then perhaps I should have held you to that commitment?
If I wasnít meeting my co-workers, I probably wouldnít have met you until 6:30 anyway, as I donít usually leave the office until around 6 pm due to traffic. When I found out where they were going I figured I could meet them for a drink beforehand, since it was in the general direction. I knew you usually leave at 5 so I thought perhaps you might like to join us and then we could have dinner.
If I offended you, I do apologize as that wasnít my intent. I was merely trying to accommodate all parties, and perhaps get to know my co-workers a little better in the hopes of developing some friendships in a new place. I thought you might like to join us, as they are fun people and I thought you might like to meet them and vice versa.
I feel like Iíve tried to be as supportive as I can of you with dealing your parents and brother and your job search, but I canít ask anything in return? Thatís just wrong."
Since we didn't agree on a time, was I out of line in letting her know I'd like to do this happy hour? We didn't set a specific time, and the time that I was proposing was probably when we would meet anyway. I think her last email - where she said I should have "consulted" her, really made me mad.
Additional background: this cousin and I are the same age. She recently moved home with her parents for financial reasons, and is always complaining about having to live with them, and dealing with them enabling her alcoholic brother. She has a fairly decent job now, but claims she can't afford to live on her own. She's always complaining about being at home with them, so I honestly thought she'd like to get out of the house. I had no idea about the interview - I knew she had applied for something, but we aren't allowed to ask about her job search.
I probably didn't handle this the best - but was I being unreasonable in my request? It's hard to judge sometimes when dealing with her.
