Rude first date asked about my sex life

Dear Pastor,

I met a man and we went out. We did not even get to know each other well before he started to ask me how much money I made per week and how many boyfriends I have had.

I told him I was not interested in him and it was good knowing him. I got up from the table and walked away. My girlfriend told me that that is not the way to treat a man. Did I do anything wrong? I would like to know what I did wrong.

P.S.

Dear P.S.,

That young man you met was very silly. He should learn to mind his own business. You did not do anything wrong. He is a silly fellow.

Pastor
