My DS8 is en extrovert unless he is with children. Last night we were waiting for a table at a restaurant and a family with a baby and a young daughter sat next to us. My son struck up a conversation with the father and completely ignored the young girl. Earlier in the day we noticed him talking to a boy about his age and when I looked at DH, we both had the same look of surprise on our face. It is almost like kids don't even cross his radar. I am constantly prompting him to say goodbye to the kids around him who are all saying goodbye to him.
