Why did I bother getting up for this ungrateful old woman on the train if she said this?

Omg ihate bitter old ladies like that who think the world owes everything to them! Dont let it get you down, I think you shouldnt have felt humiliated, its not your fault, you were being nice. and I also wouldnt have gotten up to give up my seat for her (if it was forward facing) if i had just seen that happen. But you should give up your seat the next time (if you do that regularly) because you never know, the next old lady might be really nice to you :)
