The TA won't talk to me anymore

I had him for introduction to computer programming at the local college here. At the time he said his dream was to get a Ph.D in computer science from Stanford University. I told him at the time that he was way too sloppy with his technical writing to be even considered by the elite school.

Now one year later he is still teaching at the local college, and like, he won't even say hi to me anymore.

Well, why were you talking to your TA in the first place?
