You’re out for a walk with your dogs. They’re on their leads, so one hand is occupied. You’ve been a responsible dog owner and cleaned up after them but haven’t yet got to the bin, so your other hand is occupied too. You see a friend’s car approaching, and they’re waving a cheery greeting to you. You can’t wave back with the dogs ‘n’ leads hand. But do you wave back with the other? What message does being waved at with a bag of doggy doos send?
Purely hypothetically, of course.
