Jane loves to play with a small, plastic elephant named 'Hoompra'. She carries him around, hangs him on low-hanging branches by his curly trunk, and, occasionally, takes him for walks. For the latter, she ties a string to his trunk and slowly pulls him along the sidewalk. He has no wheels, so he jiggle/slides in a way that almost makes him look as if he was actually walking.
A few weeks back, Jane towed Hoompra up our driveway, which we share with our next-door neighbours. They walked out of their back door just in time to see Hoompra's string fall off.
At about this time, Henry popped out the front door. He walked to the edge of the porch and looked up the driveway. He saw Roy (our neighbour) re-attach Hoompra's string and give him back to Jane, who proceeded to pull him the rest of the way up the driveway. Henry was aghast.
Henry: What about me?
Erin: What? What do you mean?
Henry: I want one!
Erin: 'Want one' what?
Henry: A pet rat! Roy just gave Jane a pet rat on a leash! Where's mine?
