is it a sin?

Along the same lines as Rachael's TMI and Anna's Cycles (I hope I linked those correctly), I have a few words to say on the same subject. The other day I was working with Mr. Gregory Sanderson, aka, Mary's ex-boyfriend. He has become what I imagine a little brother would be like: extremely annoying at times, especially when he knows I'm already not having a good day; he knows all the right buttons to push to drive me absolutely nuts. Well the other night I was feeling especially irritable, and I snapped at him a bunch of times. I couldn't help it. I'm sure some of you understand how difficult it is to control your emotions when you're being hormotional!

So here is my question: is it a sin to be hormotional? Last Sunday I wrote Chris a note asking this question during our sacrament meeting. Later in our Marriage and Family Relations class we're in during Sunday School, we were learning about responding to challenges and conflicts in marriage, and someone in our class brought up the point that sometimes it's hard to control your emotions, but you can control the way you react to them. For example, in my case if I were feeling hormotional I would never snap or yell at my manager Curt, but it came so easy for me to snap at Greg. So I guess I can't blame my outbursts on the fact that I'm a girl. Maybe I should just warn Greg to stay as far away as possible during certain times of the month; that would make it so much easier for me! He's pretty much the only person that makes me angry. I guess that's what little brothers are for.
