No, not really

Today I spent two hours in Room E222 having a wonderful conversation with Mr.Perlman (10th grade English teacher). By the time I left it was 5:40pm and the sky was already dark. It was cold outside and I was only wearing a thin jacket, so with my hands shoved into my jean pockets, I hurriedly walked home. I walked past a tall, hefty, Middle-eastern male who despite his looming figure is definitely a high school student. Five seconds after passing him, he turns around and starts talking to me:

Him (in mildly accented English): Do you go to Washington High School?
Me (turning around to face him): No, I don't live here.
Him: Oh you don't go to Washington?
Me: No, I don't live here. (I register that this guy is pretty dense)
He looks fairly harmless, so I slow down, but continue to walk backwards. He catches up.
Him: Really? Because you look like a girl who goes there
I'm thinking, great, I look like an asian teeny bopper. Fantastic. And I thought I outgrew that phase. At this point we're walking side by side, me avoiding his stare.
Me: No, I don't live here.
Him: So are you visiting relatives?
Me: Well I used to live here, but I moved away.
Him: Oh okay. Well I wanted to talk to you cuz you know you have a nice ass.
Me: Oh, uh, well, thanks. (I give a half smile).
Note: When confronted with creepy people hitting on me, I lack any ability to be witty, sarcastic, or rude. Surprising, given my usual temperament.
I walk into the parking lot of the apartment complex to my left. He doesn't follow. I think we're done talking but then...
Him: So uh you wanna do it?
The only thought that enters my head is "wtf!?"
Me: What?
Him: Do you want to come along with me?
Me: No, not really.
I walk away.

This rendition of our brief conversation doesn't really do justice to the awkwardness of the whole affair.
