What happened to Chivalry?

When I ride the train every once in a while a seat becomes available. I generally look for a woman in need or a child before I sit. However I've been noticing lately that the tried and true practice of giving up ones seat for a pregnant woman 1. doesn't happen as often as it should and 2. only involves a man and woman. Do women have no sense of respect for their sisters? I've seen a woman look right up at a visibly pregnant woman and keep on siting. Not even checking to see if said pregnant woman would like a seat. This leads me to my next question. Why are we as men giving up seats to women when they won't even do it for themselves? WTF MATE?

Has it always been that some women just expect respect and courtesy but not to give said courtesy? I will continue in my crusade to give up a seat to the common lady (especially if she's cute) but it's not easy. It's not easy seeing these women sit and ignore a pregnant woman on her feet. Is it the idea that she has to deal with HER pregnancy on her own? I don't get it, but maybe you do.

I need some feedback people.
