I picked up the instruction manual and read. “Oh, I see. It has a safety feature, the weight of a person in the seat causes the wheels to lock unless the harness is fastened. Let’s try that.”
“Really?…Fine.”
The chair had a pretty elaborate harness. I put he harness over his shoulder and pulled the and clicked it into the back of the chair and pulled the crotch strap up and clicked it into the harness. “There, all safe and secure,” I said.
“Great.” he sighed.
Now it rolled very smoothly. “This moves great.” I said, “How’s it feel.”
“Pretty good actually,” came the response.
“Ready to try it at the zoo tomorrow?”
“Sure.”
