> Men and women can't be friends. Eventually the sex gets in the way.

I think this is true when men have one close female friend, but if you have three or four, not so much.

From the other direction, I haven't found it to be true at all in my personal experience; when it's happened, it was clear that the women began the friendship intending for it to develop as a courtship, and I just didn't notice until it became blatant.
