Random Run-ins

I have noticed quite the dichotomy in my life lately. Who knows what it really means being that I don't believe in Karma, or a Karma-like thing that makes everything equal out but apparently I may be wrong.
So on Sunday, I went to the Flaming Lips show at Red Rocks. To my knowledge i didn't know anyone else except my friend and I that were going. Hanging out on the steps, I noticed a woman i met a in may at a friend's birthday party. We did the "eye-contact: I know you" type things. And she said "Hey I know you from Jarvis' right!" and that was about the extent of our conversation. Really nothing exciting right? i agree, but the exciting thing is that people do have common courtesy and say hello to aquantencies.
Now here comes the ying-yang opposite. Last night, I was at coopersmiths with a friend who I hadn't seen in years. We were on the patio just hanging out and talking. About an hour into our dinner, this guy comes up, with girlfriend in hand, and just stares at my friend.... Then he says... "Bethany?!? oh wait... your not Bethany." So i try to start a conversation and say hey, yeah Bethany is in Taiwan. But the guy just ran away, and made a really awkward scene.
The odd thing is that I have met this guy at least six times in the past and have been introduced to him, and carried on conversation with him... Yet he never remembers my name.

Well for the few that have been privy to my interactions with this guy, I guess i shouldn't be supprised. But really I find it offensive that I know his full name, where he goes to school, church, and what he is studying, and I really don't like him... But I at least remember him and have civil interactions.
So the dichotomy is, one girl i met months ago and we had a nice stop-n-chat at a concert even though we really know nothing about each other, and on the other hand apparently I am not worth remembering... For some reason this really annoys me that this happens.
I know i may sound a bit out of line, but really, I would have hoped the guy I met a church function would have taken a human interest in me. But really it was the girl who probably has a substance abuse problem and has significant issues that at least cares about people she meets.

How's that for over generalizing.
