Life advice: If you find that your mom has a copy of 50 Shades Of Grey it's best to just leave it alone. If you find she has this many placeholders, it's even better to let it be. You don't need to know what deviancy your mother is into.
I don't care how much more dangerous it is to use pens on a Scantron test. Pens never did this to me. I don't have OCD, but seeing stuff like this might put me over the edge. I need something to decompress after this.
