How to get rid of a CLINGY friend?

Well you're never gonna make any good friends if you're rude. I had the same problem myself. It's best if you talk with other people. She won't be as likely to in, but she still might. If you're sitting at lunch with somebody and she asks if she can sit with you tell her some other time. Eventually she'll see that you don't talk to her and she'll dump you cuz you're boring to her. It seems to me though that clingy people find other clingy people and become best friends with them.
