From my expirence there are no such things as friends that won't stab you in the back atleast once. There are good friends but never true. I have spend my years on this earth making friends and having those friends turn into enemies. I have had several friends and now a lot of them are enemies of mine. If a friend that you have stabs you in the back never be thier friend agian, they will just keep stabbing you in the back. Many people think that your friends are forever but rarely is that true. I have had the same good friend since the 9th grade. He is one of the most honest people you will come across nowadays. But still he remains unlike the rest. He will always stand out in the crowd and thats the way he entends to keep it that way. Many friends will come and go but heres a little poem I read somewhere just for your info....
False Friends
False friends are like autum leaves,
found everywhere!
True Friends
True friends are like diamonds,
presious but rare!
Friends will come and go. But the saying goes keep your friends close but your enimes closer.
