A Kids Growing Pains

So yesterday my son decided to come home and write a note to me saying that he was at the park. I dont know what possessed him to do this because he has never been allowed to do this ever. He is not old enough to just come home and write a note and say, "Im at the park". Who the heck does he think he is... "ME".. Yea right.. He is not going to do all the stupid things I did when I was a kid.. Lets just say that he learned his lesson on this one and we dont expect it to happen again. I love my little buddy and he thinks he is so grown up. Then today he tells his mom to "SUCK THIS". WHAT!!!! I looked at her with dis belief.. She went off on him... He thought he was joking because he had farted and told her to suck his fart... GROSS yea.. but when I hear the words "SUCK THIS" it usually doesnt mean to suck a fart.. He is only 9 and is innocent but he now understands that he must watch what he says and its not ok to joke in that mannor. Gosh.. Whats next.....
