Can a Man and a Women be just friends?

[wafuplayer]

I've seen this discussion many times over for years now, and recently I've gotten into a debate with someone, who insist that a man and a women cannot stay just friends, that it'll always lead into something further. I disagree with him whole heartedly as it felt like it was an insult on my own personal experience, that I'm with my female friends just to get in their panties in the future.

Anyway, I wanted to see what the people of these boards think, can a man and a woman be just friends?
