Don't Know What's Wrong With Him

I wish I knew what was bugging him tonight... He's been bitching about everything.... I tried talking to him to find out what's wrong but he just got really snappy with me....So I'm hiding in my room.... I hate when he gets in one of these moods ....It's like it's his turn at having pms....Rather sit in my room than give him a reason to yell at me..... Everyone has bad days but it seems to be more than a bad day....One of those times I really wish I could read minds....I don't like arguing.... Waste of emotions to me....
