If a person subtly mocks you because they think you are trying to impress people with how clever or?

intellectual you are, is it indicative of a jealous attitude? I mean when next they see you they play 'dumber than their mark' pretending to be very stupid and unaware of very simple concepts that you both are aware of. In the past, any of the clever things you might have said have really been out of a pressure to say something in that moment and not like being just a random person walking up to another and trying to make them feel stupid. This is a seminar and two girls we are speaking about. Is it a likely case that she just wants to embarr you, she is jealous of you, or she thinks you are an idiot?
