I understand that sometimes it is important for kids to play inside, even in busy places, but I am tired of parents letting their kids loose in doors with their scooters and rollerblades and all sorts of other things that should be used outside.
I don't mind if a kid bumps into me because they are walking and not paying attention, or even if they bump into me because they are just horsing around. But to have them hit me going full speed on their scooter because they can't be bothered to play outside? That is lame.
