"Sarah, why are you so quiet?"
This is a question I have heard multiple times in my life and I am sure other quiet people have too.
Sometime last year I was at a social gathering with people that I didn't really know very well. I didn't say much in the discussions and the only time I spoke was if someone directly spoke to me. Out of nowhere, someone in the group asks, "Why are you so quiet?" My immediate response was. "What do you want me to say?"
