The friend I've known the longest (30+ yrs) has been dating a retired performer for over a year and while she's a train wreck (kid, fucked up family, shitty job, etc) she is actually pretty intelligent, fun to hang with, easy going and all around a decent and interesting person. While I'm sure it's going nowhere long-term, nothing is so broken that he wants to end it. And she has the best stories about soooo many people!
She also is good for bringing old friends to parties just to make everyone gawk at the porners.
My friend has yet to report any STDs, drug use, insanity, theft, infidelity, or an inability to to control her gag reflex. And she does anal.
