I am a middle aged harridan who has had/still have children of mine which is precisely the reason I dont want to have to engage with any one else's when I've been looking forward to peace and quiet on a train, or anywhere else. Been there, done it, dont want to do it with yours.
Hear, hear!
The more I read the OP's posts, the more entitled she seems to me. Yes, we should all extend courtesy to others and that includes you OP
You are not special just because you've reproduced, to anyone other than your family & friends, that is, but you seem to think you are, and that everyone should treat you as if you are golden. Well, you know, I'll come out & say it: I do have an important job, I work long hours, and I travel quite a bit on trains. I have a lot of work to get done, even on a train journey. And sometimes I'm cutting it fine between meetings, so yes, I'm rushing to get the next train, or to make a quick change at Reading, or Crew, or New street.
So excuse me for getting on with my life.
But then I think, you'll learn ... come back in 25 years time and tell us about how middle-aged women are treated. You'll be one then. See how it feels.
