Why do you tell people to give up their seats when you get on the bus, and why do you have the strength to square dance at night?

This will not be a set of people, right? Doing exercises in the square of the elderly, mostly through their own exercise, and strive for good health to extend some time, as little as possible to others, less trouble to their children. When they are healthy, they will be 'later' to drag others and their children down. Square dancing and square exercises in the square is not the same thing as 'giving up your seat' on the bus, is it?

I never get on the bus to sit if there is a seat, and if there is no seat, I stand, and never sit in a seat that someone else has given up. I always say I'll get off at the next stop. I think, the pressure of young people is not small, work all day, tired, see the elderly, they can not sit down, let the elderly sit, I admire such young people. I praise them.
