Mo getting huffy with me again.

I hate it when Mo is always getting huffy with me, again. As of today she always have the last word. I'm sick and tired of this with arguing and the fighting. It's always my fault. Why is it always my fault? This has been the worst year of 2011 for me. Everything is falling to my fault. Mom is always siding with Mo. That's just not fair. WHY? Everything this year has been negative for me. It's not fair! I wish that my sister would stop getting huffy with me everytime.
