So what do y'all do when there is a person who you see almost everyday and she or he keeps approaching you no matter how uninterested in him or her you try to appear?
Tell them you're not interested and ignore them.
Be extremely passive aggressive until they leave
Ignore them or just be blunt with them.
Be assertive. Or, change your appearance.
Mention something about leprosy. Or you can try the "I'm a loner, Dottie, a rebel" approach.
I would suggest to tell them straight forward that you're not interested in them. Better to be honest than to keep them thinking they still have a shot.
Completely ignore them and stare plainly into their eyes when they talk to you, with a bit of an underbite, and live with the guilt when they get the hint and leave you alone. It's worked for me many times.
Worst part for me is when I feel bad and are nice to them again, and then they start talking to me again, and then I repeat the process until they call me a jerk/douche and then I say, what did I do? I never said I don't like you, and then they say jerk/douche and never talk to me again.
This person just doesn't get the hint. I'll look away when she talks and move when she sits next to me, but then she will move too. It's creepy as hell... I don't want to be a bitch and tell her flat out that I don't want to talk to her. I should pawn her off onto someone else haha
