It drives me nuts!
I know some are just making conversation but some are just being nosy good for nothing so and so's.
I especially hate them asking, what university do you go to? Where do you live? Can I come round when your friends aren't home? What way are you going home? I had one client who went to repeat everything and I mean everything! He gleaned about me from our 1 hour meeting (it was all wrong by the way.) on a forum. He then had the cheek to say on the forum I wasn't forthcoming with any details about myself/wouldn't answer his questions.
That's why I hate personal questions. They just want to gossip.
my entire backstory is fake. Where I live/study/siblings/ family/ my "real name" etc.
I don't tell them personal information because I don't want it to bite me in the bum one day because I upset them and then they out me or something similar.
I once banned a guy from seeing me for telling me stuff about another escort! Really personal stuff. I told him to fuck off and stop discussing other peoples personal information to every Tom dick and Harry. He told me that he didn't have "much else to talk about and Seeing escorts was the only exciting thing in his life" I wanted to tell him to get a life!
