Diary in English

I helped a boy who couldn't ride due to an insufficient balance on his IC card and looked like he had no cash on the bus. So I paid his charge.
If I were him, I would cry. At this time, I helped myself, and I want to relief from helping him.
I didn’t do that for the boy, for myself. I don’t care if it’s called selfish, selfishness goes and turns to altruism and it would be vice versa.
