<human>: So I see this chick (19 yrs) fairly often recently at the bar. Known her for a while is she is a (formerly) close friend's (22 yrs) sister. He's not particularly close to her (he's been away from home for about 5 years); however I see him on campus often as we grew up together and are in the same program (I'm in first year, he's in third). Her and I almost left together tonight but I kind of avoided it for unrelated reasons. Now she's texting me saying that she's .. um, DTF, whenever I'm down. I'm not promiscuous but I know the difference between a fuck and a crazy chick, and I get the impression that it's the former. I don't lie though so if it ever came up in conversation with my friend I wouldn't deny. Is this dangerous? My impression right now is that it's not, but I've gotten in trouble before.

Give me the gist of the text in a nutshell
<bot>: My childhood friend's little sister wants to bang, I'm down, but isn't there some taboo against doing that?
