It's a Small World:

I went to the cast party for Grease yesterday. In a weird coincidence, the dad of the person who hosted the party was actually a teacher I had at ACMA. It was pretty strange. I showed up to the party and I suddenly realized why her dad had looked so familiar. It was quite the perspective shift, since I have a lot of negative associations with this guy (his Technology class was the most inane thing ever, and he could never get my name right, even after months of it [good thing my math schedule meant I didn't have to take a second term of that class]). It was weird, trying to separate my old perspective from the one I'd built up of this guy over the past week.

Yep. It's a small world, I guess. Just can't get over how weird that was for me.
