I was 27 when this happened (so, 10 years ago). I flew out to San Diego for my high school best friend’s wedding. We’re from NY, but he went to grad school out there, met his now wife, and stayed. I’m pretty sure I was the only one from our high school friend group who went, there were a few other college/grad school friends, but it was mostly family other than that. Oh, also my high school principal, who happened to also be best friends with my friend’s father, but that’s not important, just funny.
The only other person from my high school who was there was Lizzie (name changed). She was 2 years younger than us in school, and she happened to ride the same bus as me. I think my friend introduced us when she was starting her freshman year because their parents were dating, and eventually got married. Lizzie and I would talk a lot on the bus, especially since we were both very active with after school activities (she was a cheerleader… yes, really, I’m not making that up haha), so we’d both end up on the late bus together a lot. We never really hung out outside of school, other than the few times I went to my friend’s dad’s house to hang out. Even then, we’d usually just say hi, and then we’d kind of go do our own things. But on the bus rides, we were actually pretty close and would talk about a lot of different things.
