Mental Scream

I feel like screaming right now. How can someone in their 50's be so ignorant? All I ask is that she stay out of my paperwork until I'm done. She can't even wait for me to open the God-Damn mail before she is rifling through it! Everyday I get on her about it but she doesn't seem to remember day to day! It's very irritating. And when I do yell at her, she takes offense to it and says I need to be nicer? We are grown god-damn adults! Deal with it or get out!
