When I first entered the playground, I was overwhelmed by the incredibly active 10-year-olds. They dominated all the games, while my 3-year-old cried every time they touched something, even throwing it at my son's face. I reprimanded him, even though there were uniformed ladies there, but he just casually tidied up his toys without caring what was going on around him. Oh well, I only went there once, because I was really worried the entire time.
