How Does She Do It??

Daughter #3 seems to know when I have my head down on the pillow. Tried to take a 10 minute nap on the sofa, and sure enough she called 4 minutes into the nap!! How does she know???

Now, we all know I don't do math. So I purchased a cheap calculator (with large buttons for The Old Man's fingers). Now it has gone missing. Could the scissor thief turned into a calculator thief??
