Lol, come on, admit it, it's comfy up here on the girl board.
I think you pretty much said it the way it is. Childhood friends are ALWAYS friends, and the other ones usually end up with him "trying to get some," eventually, but finally settling for being friends. It's also great to have a "work husband." Someone at work who is like your soulmate and you're like glue from 9-5... causing everyone to think there's something going on but there isn't. Usually you're just talking about who's getting fat, or bitching about the losers, and then at the end of the day, you go home to whoever...
Unfortunately, sometimes the whoevers at home, get jealous.
