Male coworker is starting to be rude. Why?

[Anonymous]

Ok so he talks to everyone but me. How nice of him. I uses to try saying hi but stopped once i realized he never said hi first to me. Now today i said hi and he didn't say hi he just replied about something i needed (for work). Wow. Just getting rude.

Either ignore him, or ask him why he's acting like that way.
