Not an exchange I had, but one I saw. I am travelling to a specific city in my HomeCountry in the first weekend of October for a milestone event in my life. My immediate family are all travelling to join me in Xcity for this milestone event. I have extended family living in Xcity. Seeing we're all going to be there, my Dad suggested we also do an extended family event over the weekend as well, which I'm super happy about. So my Aunt Rita and her family are travelling to Xcity as well to join us for that.
My fairly new sister-in-law is travelling a fair distance (with my brother) to get to Xcity, and will also be visiting another nearby city where she used to live. So she posted a status update on FB to let her friends know she'd be back in the area, saying "I'll be in Xcity the first weekend in October, and then down in Ycity for a week if anybody wants to catch up".
Aunt Rita posts a comment on it saying
"I'm going to be in XCity on the first weekend in October so I'll finally get to meet you!"I felt like saying "Why do you think
she's going to be there???" Now, I do understand that Aunt is excited to finally meet my SIL (Aunt wasn't invited to the wedding). But I'm fairly certain she hasn't actually clicked that it's not some kind of convenient coincidence, and that SIL is actually going to be there for the exact same reason she is!! Aunt Rita lives much closer to Xcity so travelling there isn't such a big deal for her. But for SIL and bro i it's a long way, and they had to put a lot of thought into whether they could make this trip or not. I'm stoked that they're coming to support me (and also that SIL gets to catchup with some of her old friends). I guess perhaps Aunt Rita was just meaning "I'm excited I'll get to see you at <the event>", but knowing her as I do, I'm fairly certain it's just a "Oh you'll be in town too? How convenient....". (There's a reason Aunt Rita wasn't invited to the wedding. Several in fact, which I won't go into!

). Some people do not make the brain connections!
