Stay!
I puled in to the crowded car park at the local shopping centre and rolled down the car windows to make sure my new puppy has sufficient air.She was stretched full out on the back seat and I wanted to impress upon her that she must stay there. I walked backwards to the kerb, pointing my finger and saying emphatically "Stay! Stay!"
The driver of a nearby car, a blonde, gave me a strange look and said, "Why don't you put the handbrake on?"
