Kids....more specifically TWEENS!!!

Help me to understand...I love my 11-year-old son, but sometimes he makes me so crazy! It doesn't matter what I do for him, he thinks I'm out to get him?!?! I try to help him study for a test, he thinks I want him to fail; I help him pick out some clothes, he thinks I'm trying to make him look like a dork!! I just can't win! I'm not liking the "tween" years already!! Is it just me or are they getting more difficult? I just can't remember ever acting this way with my mom...UGH! Okay, enough, I just had to vent!!!!!
