My Mum Pisses me off

Ok so i have to get in 50 posts and i just arrive home and trying to get started on my performace task for english. So my little sister is on facebook obviously because she always has nothing to do and i tell her to gett off because i need to do something more important then you being on facebook. She gives attitude and then goes to my mom who blows a **** because i kicked her off when she has to get off. If i dont do this i fail, but my mom thinks she thinks she knows everything. Mom is going to kick me off the computer and remove the computer just because i have to finish up this freaking 50 posts.
