Annoying former friend? (see below)
okay, so I had this friend, let's call her K. she was my best friend from 2nd-6th grade. during sixth grade K started to really get on my nerves and soon I couldn't handle being around her, so I stopped being friends with her. luckily I didn't have any classes with her last year (and also didn't have a Facebook.) well this year I have a class with her and a Facebook, and she has sent me a couple messages asking if we're friends again. I'm better off not being friends with her because she always made me feel bad (she was basically what you'd call a poisonous friend.) recently she sent me another message asking if we can be friends. I don't want to sound mean, but I want to her to get it through her head that I don't want to be friends. suggestions?
