Friend or... Frenemy?

How can we see the different between a real friend, and a real enemy? Friends don't talk at each other's back, friends don't make each other's life miserable, friends accept who we really are. It's not easy to have a real best friend. It's not easy to see who is our friends really are. They often wear a mask to hide their real face. So we can't see if they really nice, or it's just a fake. Too bad, at this time maybe acting is a little thing and everybody can do it. There's a possible someone who look really nice outside, but have a really bad deeds inside. And that is what I called a frenemy. Like many people said, keep your friend close but your enemy closer. And we have no idea if we have an enemy or not, maybe there's someone who really hate us, or maybe more than one. All of us have a different personality and that's one of the reason of this 'hating' problem. Sucks huh? I'd rather be alone than to be with someone who pretend to be my friends when the truth is they are my enemy
