That makes sense - I kinda do the same thing in a very ADD scribbled corners on receipts, envelopes, and other bits of paper I will never see again.

I got the several books at once thing from my pops. When I was a kid if he made me mad I would move all his bookmarks. I secretly live in fear now that someone in my life will figure out that dirty trick.

The many books at a time thing is problematic right now though since I am reading so little. If you spread that many stories open in a huge swatch of time things get fuzzy.
