Back in the fall, I joined an activity group. Not a bowling league, but let's go with that. I mentioned it to a coworker, Melissa, and she joined, too. Since she drives right past my place to get there, she always picks me up. I've offered to drive sometimes, but she strongly prefers to drive because of carsickness. Friday night was a friends-and-family night for the league, with a house party after. I was really looking forward to the party since we're still new in town, and Melissa picked me up as usual.
Half way through the night, Melissa introduces me to her mom, who has just arrived from out of town. In front of her mom she says to me "Now of course you're welcome to join us for dinner after (though by her tone I wasn't really!), or I can take you home first, whatever you want," but follows up with "Except your DH is coming later, right?" Well, no he wasn't. He'd had to work for most of the night and had thought about coming, but was under the weather and had decided to just go home. By this point of the festivities, he was already in bed, if not asleep.
I asked (I hope politely!) when her mom had decided to come - well, about a week ago, though Melissa hadn't told me. I got the impression that she really didn't expect her mom to come all that way and had just figured that things would work themselves out. I ended up telling her to just go with her mom at the end of the night, planning to walk home, but was offered a ride to the party by another league member. I went, and had a nice time.
Now, I didn't address anything directly with Melissa, and I'm not sure if I should. But I'm frustrated that she hadn't said anything to me ahead of time - I could have driven myself, after all. Advice for what to say at work tomorrow?
