She's an older woman and to be honest I'm not entirely sure she knew what she was saying when she said "hook up." I think to her it just meant get together not have sex. Or maybe it's a secret code word women use that I'm not aware of regardless of her age. It does seem to me that younger women would think it would mean sex but not older women. I could be wrong though. I just don't think an older woman would say it like that because she wouldn't want to seem slutty.
All I'll say is despite the fact that it's all a game I do think people at some point need to make it clear what their intentions are. I see nothing wrong with saying "well don't get your hopes up because I"m not really looking for something serious." They're going to find out sooner or later so why piss them off later when I can just weed out those who are only interested in ltrs. They can't label me a player with a straight face if they **** me when they already knew what my intentions were.
