Pregnant Woman Left Standing On The T...

Why is it a non-pregnant woman sitting will offer a pregnant woman standing her seat on the train before a non-pregnant, NEVER experience the joys of bloated kankles and tailbone pain along with not just exclusive to the "morning" sickness, man sitting? Is it because this said "non-pregnant seated man" does not see this oh, so extremely about to pop "pregnant standing woman"? Maybe they are too busy stretching their legs into the two seats beside them to notice. I'm not really sure. But, FEAR NOT you seated non-pregnant man! I've got this one. The full-time working Mom with a massive migraine due to not sleeping the night before because she was up with her 20 month old will gladly offer said "pregnant standing woman" her seat. Just don't stretch your knees into her legs while your busy marking your transit seat territory.
