As a child, we dragged people to and from the hall and assemblies. It wasn't a big deal at the time. My parents are now in their 70's, and they are still picking people up, my mom gets annoyed that they seem to be the only ones asked to do the ferrying around. They also get stuck dragging people back and forth to doctor appointments and hospitals in the 'big city'. They have to sit there, literally sometimes all day, as the person gets this test done and that test done. They do live an area where there is senior busing. I don't know if they have ever made that suggestion to these people or not.
No one should have to give a ride to people who are incontinent and not able to care for their own hygiene. That is just gross and extremely unsanitary. If the incontinent person was able to use a diaper product and not leak all over everything, then that changes things.
