Hi Steve,
Our oldest is 15 and is at that age where he feels embarrassed to do "little kid things". With mom & dad doing it too, making it a whole family thing to dress up and have fun, it helps them to not feel awkward or out of place. I did have one lady get pretty close, looked directly into my mask and ask me "How old are you???"-ha. I didn't reply, just held my sack out for a treat.
