I'm on secondment at a bank. At work, I'm seated next to an older woman (mid 50s) not attractive, who always tries to make conversation.

Lately, she started telling me how she would love to find an artist to take her (sexually) and how artists are different in bed and what not. She says, you won't find anyone who's as honest as me blah blah.

Frankly, it's just very childish and makes me feel uncomfortable. I got so annoyed today that I almost said, "Look, you're being obnoxious and childish in trying to be edgy and cool; please stop, I don't care".

I genuinely don't give a fuck and find her to be a bore and annoying.

How would the more experienced TRP hands deal with it? HR is out of the question for now.
