This question was also put to me by the sixteen year old boy from a Himalayan country about four years ago.
“Every morning I go to school by bus and go to the bus stop early to get a good seat. However, it most often happens that very soon on the journey and old person or a pregnant woman boards the bus where, because the bus is crowded, they have nowhere to sit and I give them my seat.
Should I go early for the bus when all I seem to have to do is give up my seat?”
I have very rarely ridden on buses, mostly I drive, where I give up my seat for no one. Though I do pick up Hitchhikers 😉
As to the question – the only answer that really matters is – what really makes you feel best?
Ask the question every time, to the deepest level you can reach, and see what answer you come up with.
