When uninterrupted, I can watch my cats groom themselves for a good 25 minutes before realizing I ought to be doing something else. (Did it Saturday).
I count purchasing medium for my acrylic paints as one of the highlights of my weekend (Did it Sunday).
I wander the stacks at the Vancouver Public Library for hours (Did it twice last week).
I consider people watching on the corner of Robson & Howe to be intensely educational (Need to do it again this week).
Give me one idea and I can segue a circular path until forcibly stopped (Give me paper & pen and only a wrist/hand cramp will stop me).
