I am sure they felt that same way about you many times while raising you. But they let you go, try things, find your way. My daughter is worried about us, has put a tracking system on my phone so she knows where we are. Accidents happen, I am sure he learnt from that one, and will do fine. Sometimes you just have to let your parents grow up. This is from a Mom that is getting tired of hearing I can't do something because of my age...I am 56.
