Off the Force

So I have this friend.
Acquaintance.
More like someone I used to know.
I'd like to know him again (But not in the Biblical sense, of course).
But he contradicts everything I say.
He makes fun of me when I try to be nice.
I'm kind of wondering why I try.

Remember when I was back in college, taking statistics, and tutoring that good-looking guy? He was cute, to be sure, and I didn't mind him walking me to my acting class every Tuesday and Thursday. It was delightful, even though my heart was actually across the country with someone else at the time. I felt helpful, and truly, I felt cool.
But then remember how he suddenly stopped sitting by me? And how he didn't talk to me? And how when I finally called him up on the phone he said that the very thought of me made him want to vomit?
And do you remember how he told me that I just didn't get it, and that the meaner he was to me, the nicer I was to him?
For a long time, I wore that memory like a badge of honor. But I'm tempted to turn in the badge and throw in the towel.
