In case you haven't noticed, I'm big on friendship. Women need girlfriends. Husbands and significant others are fine, but they don't GET things like another woman does.
For example, have you noticed that men are completely oblivious to when you wear a new outfit? My friends always notice when I am wearing something new (new by way of garage sales, of course). And then there's the whole shaving hair disposal thing. Men don't see (or care) when they leave nasty little hairs in the sink.
I figure the man/woman difference thing can be explained by asking yourself one simple question. Can you really trust the advice of someone who uses the same soap for both his hands and face?
