your best friend is your worst enemy

yes it's possible because one tends to share even the darkest secret to a best friend which can be used against him or her.

When you think about it, it could be true. an experience of mine would be this girl i liked. my buddy started talking to her and now shes talking with him and barley paying any attention to me! so i pretty much am making my mind up with what i plan to do with my friend. wheather i need to draw the line with him or tell him to stop talking to her, or i wont be his friend. if it wasnt for me he wouldnt know her, and i was talking to her in the first place and he knew that. so yes your best friend can be your worst enemy. just think about how much you talk to your freinds about personal experiences going on with your life. they somehow get involved with them and can sweep them from underneith your feet.

I WOULD AGREE. Most of the times when your friend becomes your enemy... they would definitely be able to destroy you, use the things they know about you to hurt you because you are friends before you become enemies...

Yeah, it can happen to me.

No untill misunderstanding happens. If your friendship is true there is no way for that. Dont misunderstand your friend then it willpay.
