Aiden Attendance
Da name of a super-caring dude who is permitted to ride along for free (i.e., "companion fare") on a bus or plane because he provides cheerful assistance for a physically/mentally-challenged individual who is also taking said public-transportation service.
If two handicapped people travel together and they each provide necessary assistance to the other (i.e., perhaps one can hear better, and the other has clearer eyesight), could they BOTH ride for free by each of them's claiming to be nicknamed "Aiden Attendance"?
