Sometimes there's a person that just gives you a certain uneasiness that makes you not want to encourage a friendship. There's a guy like that at my health club. He's always hanging around (not even working out, just chit chatting at the front desk) and I catch him staring at me (my guess is that any new female attracts his attention). He positions himself in my path to start up conversations. I am not rude, but keep conversations short. The thing is, I'm new at this place, and I want to make friends with other (non-creepy) members. I don't want other people to see me giving him the cold shoulder and think I am unfriendly. My friend says to just suck it up and be friendly to him, but ugh, he gives me a weird vibe.
