i think so

sure it is. why not? I also do that when I greet my best friends (who are girls).

Well... I guess it depends on how 'deep' the kiss is
No, I don't think it's something bad or disgusting - as far as it really looks like a friendly gesture. A small kiss is ok.

'One rose can be my garden,

one friend - my world'

Yeah I think that is fine, for a best friend,
Best friends are like family, Gotta show love to your family right??

Yes, I think it is OK. I love my best friend like a sister. She is always there when I need her.

No, guy/girl whatever, I find it inappropriate.

THE CHRISTIAN LIFE WITHOUT PRAYER IS LIKE COMPUTER HARDWARE WITHOUT THE SOFTWARE!!!!!

It depends on the country you come from. In some places (I forget now) it's friendly to hold hands, but say, in my country it's not really, it's something couples do.

Never argue with an idiot. They will only drag you down to their level and beat you with experience.

it does depend on where you're from. for me, a kiss on the lips is something couples do, not really something that friends do. a kiss on the cheek is more of a friend thing.

There are girls all around me kissing each other as they meet. As a greeting, that is.

But you do have to be sure that both of you are in on it, that it doesn't mean anything else than what you want it to. I think that's important.

It wouldn't do for two best friends to go around being suspicious of each other's intentions, would it? I say this because that's what happened to a friend of mine. She got really annoying and paranoid, saying stuff about her best friend that a best friend shouldn't. She thought her best friend was in love with her.

Guess they weren't really best friends on a deeper lever, as they didn't know each other that well.

Am I making any sense?

Don't play stupid with me. I'm waaay better at it.
