Peter, my 29 year old was a dirt magnet! The 12 year old is a grub, pure and simple. Somewhere along the line, they discover G-I-R-L-S, and things change! They still get grubby at the wink of an eye, but their acts have cleaned up considerably. Girls? Three of them, and when the youngest was 15 and the wife was pregnant again, I told her if its a girl, I'm outta here! Wouldn't have, but she knew what I meant. The youngest two girls were hell on wheels!
