It stems from the fact that I know one person from the group of friends she was with the night we ran into each other. That one friend was not in attendance yesterday, and the rest of them have seen me once or twice. Therefore, when they were looking out for me, they missed me.
So three pieces of good news:
A) She did show up.
B) She was disappointed that I wasn't there.
C) I'm a dork, but I like it. (and not a loser)
