Im a girl but that doesn't matter so whatever.
So there's this girl and she and I had a few common friends so we would have very brief conversations. But then we both found out we were doing track (she's a thrower and im distance) so we talked a little more. She asked me dor high fives and i would sometimes give them to her. But then she got really annoying. Like when me and the other distance runners were stretching and doing core, she would randomly say " HI ******" (my name) in dead scilence so everyone could hear it. (It was embarassing in my head i wanted to die) But then whenever we do speed workouts on the track she and her friend would try to get me to high five them when I pass them during my run/rep. IT WAS SO ANNOYING LIKE HOLY SHIT I'M TRYING TO RUN. WTF. But then the other day she asked me for a high five and I said "no" in a monotone voice. I'm trying to imply that I don't want to talk to her. I'm honestly not in the mood.
How do I get someone to understand that I don't want to be friends with them? I don't want to talk to them. I'm trying to be polite but it's hard sometimes.
