How fast they grow?

My Son is now in 7th grade and it seems everyday he's maturing faster than what I want him too. I did however the other day see some kid in a tuxedo shirt walking from the High School. I know its not picture time yet as school just started. Kids these days are funny, just like how it was back in the day when I was in school. In fact last night while at my friends house we were discussing something and her daughter goes..."You guys can't talk like that!" Your so not cool.
