Layers of kindness

I usually head right to the seats at the back row when I get onto a bus. My rationale on my behaviour is that, I think it is more logical to allow the front seats to be occupied by the seniors, disabled and the ones with huge bellys. Another side of my brain argued, my behaviour was a mere deception to all. I chose to sit at the back row because I stand a 1% chance to give my seat up as these seniors wont really make the effort to walk all the way to the back row.

I wonder, am I the only one with the same thinking or which thought actually comes first?

Anyway, I was sitting very comfortably in the LRT yesterday, day-dreaming about something which I could not recall, a lady with a huge belly suddenly stood in front of me. She was expecting me to instantly get up, but it took me a few seconds more as I was day-dreaming. This lady pushed her belly nearer to me, leaving an inch gap from my face as a hint.

I gave my seat up for her, of course.

I wonder, do these 'privileged' people expect to get what they want, at times?

Btw, she did not take my seat as she found another seat nearer to the door.
