My mom wants me to add her on my facebook!!?

Here's what you can do. Add her to your current account. Add her to a new list. Go into your privacy settings and hide somethings from her. Don't block everything from her, as you said she'll notice. So, after creating a new list and adding her, you can post whatever you like and while posting, you can choose who that post is going to be visible to. So, every one and then, share some pages and set the privacy to public so she can see it.

Hope it helps.
Good Luck.
