It's sad to see, but a lot of the younger generation doesn't seem to show respect to older folks the way we used to. It doesn't always amount to blatant disrespect, but being dismissive of their opinions and value to society is something that is becoming all too common in our society.
It doesn't always have to be this way. In fact, many Asian and African cultures tend to revere the elderly because of the depth of their life experience and wisdom. This is in stark contrast to some Western cultures where those of old age are sometimes seen as out of touch or incapable. The young man in this story is about to learn a lesson about respecting his elders that he won't soon forget.
