Bratty Kid

Why must my kid be such a brat? I love him to death but he is being so mean lately. I have read all the stuff that says this is normal but I just want it to end. All he does is argue with me and get into everything. He is also being quite a little bully to all his friends.
He is at least still being nice to his sister. Well at least most of the time.
This is just so exhausting.
Ok enough complaining now I have to go finish getting ready for my works christmas party. At least I get to leave the monsters home with dad tonight and enjoy a night with my friends.
