Not taken by surprise by Ben's antics, it took me about a minute to think of a possible cause and solution: Ben sits alone at the very back of the bus in his Convaid Chair which is strapped into a special system for wheelchairs. He probably wanted to be in a regular bus seat with his friends.
Ben is quite the popular man. His friends call his name as soon as the bus rounds the corner of our street.
There are many wheelchair positions on the bus, but Ben's spot has been closest to the ramp which is 20 feet away from the action. I recommended that the bus monitor strap Ben into one of the wheelchair spaces closest to his friends. As I said this, Ben gave me a smile.
Ideally Ben would sit in a regular seat with a special 5 point safety harness, but that would mean a bus monitor helping him walk up and down the bus stairs. At his most recent weight of 70 lbs, I believe the chair is the safest route for everyone.
So what happened to the back of the bus being the cool place to sit? Times are changing!
