If someone needed my seat and I was fit and able at that time, they are welcome to it (I have done so in the past and will do so in the future). I will also teach my son when he is old enough some common old good manners on this subject.

So MM I am not sure what your point is. Trying to say that I must be like that, which is why I don't get the courtesy in return. If this is true, then ALL pregnant women who go to the OBGYN must be like this. Very strange analagy.
