Why should I have to hide stuff every time my mom looks on my Facebook?

I feel like she's always in my personal space, and she spends her whole life shitting on mine. My Facebook had plenty of potential threats to her trust in me..stuff like racy pictures, perverted inbox messages, and just innapropro stuff. But she suddenly wants me to unblock her and let her snoop in my account. So I just spent thirty minutes clearing out dangers. Seriously why is she all up in my business why can't she just let me live my life?
