lol I had to laugh when you both enjoyed the coffee quietly thereafter. I donot think you are a snob you are just an introvert and dono speak much.As you said it does not matter whatpeople say - you will just continue to be yourself and that is wonderful.
I am very social and not an introvert but I do not always like to speak and certainly not to everyone. We can enjoy silence sometimes - there is lots of beauty and wisdom in silence.
