Yeah I'm the same way. I'm a compulsive highlighter and I often find myself disassembling pens or mechanical pencils, or folding paper, or removing the plastic coating inside a bottlecap, or balancing my glasses on the tip of my finger...The people I spend time with in meetings must wonder if I'm actually paying attention.

Yes I do, and now that you mention it, I'm sure it's two manifestations of the same behavior.

Not while reading, but I'm notoriously bad when I'm on the phone...small objects all over my house and office are in a constant state of displacement because I pick them up and set them down somewhere else while on the phone.

Haha, yes, absolutely. I always like to have something to distract my hands. Rubber erasers are heaven for this.

No, not usually.
