"Hey look Rosie! It's Pp!" I said.
Rosie gave the car a look of extreme suspicion.
"Hello Rosie!" said Pp, through the open window. "Come on Rosie! Rosie come!"
Rosie moved away, looking even more suspicious.
"Come on Rosie! Say hello to Pp! You like Pp!" I said.
Rosie's body language stated firmly : this is not Pp. Pp has legs. This is some sort of weird centaur-hybrid-machine thing, and she will not be fooled!
I give up and allow her to tow me away.
