All the time. Especially in group settings. You will be talking and behind to stutter or get blocked on a word, they just start another conversation with someone else in the room. Another part of group settings that is hard for me is when the conversation is moving so fast that I cannot get a word in. Usually this is in a witty/funny conversation. I have a good sense of humor, but my brain prevents the words from coming out and by time I can someone else chimes in. It can be really discouraging sometimes.
