Counterpoint. You can be very shy and have a conversation with a total stranger. It’s easier when there is nothink at stake: you are not asking for the time, direction, a phone number, a date or anything. You just make a comment about the weather, something you find , or funny or interesting nice (no comment on anybody’s appearance though). You are not waiting for a reply or trying to start a conversation. If it gets started, that’s a bonus. When I score one of these interactions, I always feel very good afterward.
