ok seriously, this "fake friendship" trend needs to end.

if you dont like someone, dont talk to them. if you have the guts to, tell them how you feel.. if not, dont act like everything is great between you and that person.  furthermore, dont hang out with them outside of school.

when you hear that they talk about you, confront them. dont bitch about it to all your other friends and then hug your backstabbing friend. thats ridiculous.

im not saying that you should tell a person everything about them that you dont like.  because even some of the greatest friends/people have a few bad qualities.

but  if they annoy you to the point you dont want to be their friend, that's a hint NOT hang out with them

cheers.
