Whenever someone comes to visit on a motorcycle, Cooper's main interest after greeting the visitors is to sit on their motorcycle.
Most people don't mind, but I really have to watch him when I know someone is visiting who wouldn't want him on their bike. His nails can scratch a nice paint job, so a there are a few who would rather not have him on their bike. I respect that for sure. Cooper will never understand, so it's my duty to make sure he stays off bikes he shouldn't jump on.
