Selective Memory

I was walking down University Street, Wednesday morning at about 11:25 am. Not late to class, but I have the tendency to test myself and see how fast I can make it to class. I won't leave my room until the last possible moment I can, to make it perfectly on time to class. I end up semi-sprinting down the hill, passing all the kiddies doubled up on the sidewalks, New York style, probably with a path of destruction in my way.
Anyways, I was in kind of a hurry. I ran into one of my frosh leaders whom I hadn't seen in months. I was pretty surprised that she recognized me, actually. I recognized her...but for some reason I felt like an underclassman again, just happy that someone remembered me enough to select me from a crowd and say hi. We shot the breeze for a couple of minutes, and I was happy to see her but I was also mid-sprint. There was also that awkward moment after she asked how life was, where I didn't quite know what to say. I tried to think of things I've been up to, and I reverted to my line "I'm always busy, but I couldn't tell you what I'm doing" because it seems to communicate my overall feeling towards the chaos that is university life. We said "see you around" or some bullshit, but I guess its inevitable we will, and next time it will be just as meaningless, but just as comforting. A reassurance that I am still the same person I was in August, at least on the outside.
50 feet further down University, I hear a car honk to my right. There's this dude waving manically through his window at me, a shit-eating grin on his face. It's like he hasn't seen me for three months, and all of a sudden we are best friends reunited. But I've never seen this guy in my life. I put up a hand, smile, taking a moment to make sure I don't know him, and continue on my way. This happens to me a lot. Whenever I meet someone, they tell me their cousin looks just like me, or I remind them of their camp friend, or even better..."Did you go to such-and-such Hebrew School?" One time I was telling my Dad about it in a restaurant, and 5 minutes later, the woman at the next table asked me if I had been in L.A. in the summer of 2004, because a girl had walked into her Mac store that looked just like me.
So I keep walking, thinking about all of these things, and outside the frat house, a girl in a touque (spell check??) gives me a huge grin, a wave and a "Hi!" as she passes me on the sidewalk. I have never seen her in my life either.
I touch my face. Did I wake up this morning with a new one? I look at my shadow, thinking itll show me my altered identity. But it doesn't. And furthermore, I was recognized by the frosh leader as who I was in August...did I pass out during Frosh and meet a bunch of random-ass people and make a bunch of friends that I don't remember?
It's a distinct possibility...
