That depends, because I've considered 3 different women my ATF, whose "names" are Lily, Dusty and Olivia. (Actually, Olivia really is her name.) I don't know if Dusty could ever be my ATF again, because while I enjoyed 95% of my experiences with her, at the end, she went all flaky on me and blew me off entirely, and then moved far enough away where I can avoid her if I want to. As for Olivia, she just simply quit the business. So I guess I say Lily is my ATF now, but just because a girl quits the business doesn't mean she can't still be your ATF. It's not like she went flaky too. But considering I don't see Lily much anymore, and probably would most likely see her by accident, it seems like either I don't have one, or anyone else could be it. I sometimes wonder whether the concept of the ATF is worth it.
