School Days!!!!

My 4 yr old grandson, Cannon, got in trouble at PreK today and his twin brother, Colt, came home and sd "Gegaw, he was a bad boy!" What is wrong with this picture? They have been staying at home, playing, enjoying childhood, then they go to school and wham! Everyday one or the other is in trouble. They just don't get the school thing. I laugh because I think this is such a new thing for them, they just don't have a clue that this is the begining of 14 yrs of school. I wonder if everyday will be like this.
