Some years ago, I went to a local attraction with my wife who was in a manual wheelchair, and another couple whose with wife was in an electric scooter. At some point in the afternoon we all took the park transport to another area, leaving the wheelchairs behind. Later the scooter user and I returned to collect the wheelchairs. I felt a bit stupid pushing an empty wheelchair, so sat in it, took hold of the scooter, and was towed through the park. All went well until we went round a corner a little too fast, tippng the wheelchair. I stood up very quickly before any helpful passers-by could come to the rescue of this "poor disabled man". Though the fact that we were both laughing our heads off probaly indicated that I was not seriously hurt by the fall.
