It's not about beig superior. And I think it might be different readings of the word 'respect'. I would certainly expect my 8 yo to stand up on a bus and let and adult sit down. Because he is young and energetic, and I assume that adults, like me, are more jaded My 5 yo I would prefer to stay seated, because she is more unsteady on her pins, so I'd put her on my knee so there is maximum sitting down availability.
I expect my DS, and my DD, to 'respect' that some people find things easier than others, and if they can do something more easily than others, then they should do so.
