How to respond when somebody asks "do you mind if..."?
I don't know if this is the right website to be asking this but...I realized that when somebody asks "Do you mind if...", you can't just answer with a simple "No". There has to be a phrase that comes with it, otherwise it'd be taken as "No, u can't" instead of "No, I don't mind."
When I moved to America, a guy asked me "Do you mind if I sit here?" pointing at the empty seat next to me. I said "No" and the guy and some people around me gave me looks. I got confused for a second. And then he asked me again "No?" And I finally realized what was going on and I said "No, I don't mind". It was one of the most awkward moments of my life.
I mean he was asking me if I mind or not and I said "no". Anyway, how should I respond to this question? And are there other tricky questions similar to this one? And how should I respond to them? Thank u.
