I'm really frustrated with my parents right now.  They let my little sister get away with everything, and I keep getting stuck doing her chores.  I'm so sick of being stuck cleaning up all the stuff in the house.  I don't make any of the mess, yet I'm stuck picking it up.  And now my sister never does her own chores.  I'm so sick of it.  Yet, I can't say anything, because then I get in trouble and they say that I never do anything.  I'm so sick of this!
