On one occasion, when I was just inside the lift and I saw the fat wife and his youngest son carrying heavy load of grocery plastic bags from the Shop and Save supermarket.. I duly waited for them to enter the lift.. Not even a word of thanks or a smile of appreciation from the Fat Chappati wife..
Learnt my lesson.. Few weeks after that similiar situation on a rainy morning.. Was in the lift when I saw the wife and this time her eldest son.. She gave me this hopeful face that I would wait for her fat butt to enter the lift.. I didn't wait for her and just press the lift's close door button on them.. The surprised face shown by her was priceless..
You're right brother. I have seen them on the train. The whole family would try to hog the seats. They wold expect you to give the seats to their kids. If their kids had the empty seat, they would look at the person beside and hope that he/she give the seat up. And of course, without a word of thanks.
