The Overcrowded Train

The train was overcrowded. You saw the old man get in. You so much wanted to help out that old person.
The moment he came inside near your seat, you offered it to that old person. The old man first refused to sit. Later, being forced by your generosity, he sat down. The next stop was about to come.
Another pregnant lady came in. The old man got up immediately. He offered the seat to her. She graciously slid into the seat. Few minutes later the old man got off.
You wondered wth? What the hell! You offered YOUR seat out of respect and here you have some preggy occupying your seat! Gorn!
You think you were better off not looking at or helping old folks. Ingrates! Humph!
