He understands, but his friend is quite braggy and it makes my son feel bad. Also, my son's friend is allowed to do just about anything including riding in the front seat of the car, ride without a seatbelt, ride bikes without a helmet, stay home alone for long stretches, see rated PG-13 movies, etc., etc. Of course I think the lack of safety is ridiculous, but my son thinks his friend is being treated more grown-up than he is. I have explained it and my son is smart and gets it, but his friend is always calling us overprotective which makes my son feel like a baby in comparison.
