How to tell people you don't like to be friends with them?

Well, I see where YOU'RE coming from, but at the same TIME, it doesn't hurt to be friendly. I mean, you don't have to go OUT with these guys if you don't WANT to, but speak to them, smile, and chit chat with them when they approach you. TRUST ME, it costs nothing to be friendly, especially since they are making it EASY for you to DO so. In life, we're going to have enemies, but don't unnecessarily MAKE any enemies, which is what you are LIKELY to do by snubbing these guys, or ANYONE really. AGAIN, you don't have to go OUT on the town with them or anything like THAT, but please, do be courteous and friendly. You'll go a LOT FURTHER in LIFE, and you'll have less stress, and less enemies FOR it if you do:) I KNOW that this is awkward for you, but you don't want to hurt other people's FEELINGS, or to leave them feeling like, " Oh, HE thinks he's BETTER than other people", even though you may feel NOTHING of the kind. But people tend to VIEW loners in this way. Just nip that in the BUD, before those accusations even BEGIN. I understand your stance COMPLETELY, but you have to kind of meet people HALFWAY. Otherwise, you will look snooty and stand offish. NOT a good thing. So TRY to meet people halfway with all that's IN you, EVEN though it's HARD for you. TRY. You'll get better, and BETTER at it, until you won't MIND being outgoing and friendly with people. TRUST me. I KNOW.
