This is a story specifically for non-defeaters.
A couple of years ago my friend was pregnant, and here some month on the eighth we went with her in the bus from consultation, and she got sick: nausea, weakness, in the eyes darkened... In the morning I felt good, and in general, even when I got into the bus it was normal, or a taxi called. And then it worsened sharply - the breath, the catch, the smell of exhausts, maybe the pressure changed. In the full room, the next three seats in a row were occupied by the company of men. She, with a green face, polently asked to give up a place, the guys answered so, say, and what, we are not obliged, she jumped on the fox and now blushed, tolerated, ovulated, gyggy. It was here that she was pulled out of the fountain, on all three practically, and almost lost consciousness - I picked up, and the grandmother next to her sat in her place.
Morality: Sometimes giving up a place is not only beneficial to those who give up.
