I agree with a lot of what you say, but Ive got some thoughts on perhaps why it is this way.

For starters, I think some people offer seats to others, to girls particularly, because they want to be "good" people. Its like the bible says about praying in public, "dont be like the pharisees, praying in public where everyone can see you... those type of prayers are their own reward". In the same way, making a big show of "excuse me, ma'am, would you like a seat", its like standing on a chair in a full room and saying loudly "I AM A GOOD PERSON". That type of "generosity" is actually a self-serving behaviour, intended to feed ones reputation, like those pharisees who pray to be seen praying.

Then the converse, she makes me think about the problem with most people today. In their own world, oblivious to the challenges and trials of those around her. Im reading "The Tao of Poo", and in that book it encourages us to stop being a "Backsun", which is a type of person, rushing from point A to B, always living for tomorrow, never in the now. These sorts cant help by be blind to the neighbor beside her who needs her help in the moment, why? Because, not being in the moment herself, she is blind to the difficulty of it, too busy stressing about the next thing, or equally possible and equally unfortunate, already looking to the joys the next moment might bring, blind to the potential joy in the present, such as: sharing a kind moment with a fellow bus rider, in need of a seat, and which might lead to a thoroughly enjoyable conversation.

I also like what you said about, if you're getting off at the next stop offer your seat. Some nice girl did this for me last week, she was probably 20 and Im like 40-ish, but I was struggling with a bag and a jacket and she did this. So, some girls do, do this.

Anyways, good post.
