Well if they try to screw with me, trying to get me to do dumb things, like the immature children that used to try to in high school.
I'd mess with them, not giving them a satisfying answer or turning it back on them to make them look foolish.
If they don't like me, and doesn't do anything to me. I stay out of their way, no need to kick up any unnecessary conflict that is a waste of time and energy.
