Sparky is seven months old now. Dad called last night to report a new trick. He will sit at the bottom of the stairs, and throw the ball upstairs where it sails down the upstairs hall. Sparky will go get it, bring it to the top of the stairs, and drop it so that it rolls down the stairs to Dad.
Dad thinks this trick is a sure sign of brilliance and he’s hoping Sparky will remember it today, when my mom returns from an overnight trip.
