What elderly people have you encountered who are not respectful of the elderly?

I think it's partly because our younger generation is so much more qualified and respectful of the elderly that they've spoiled them. Once I took my kids out to dinner and let them walk on their own on the way home (they had only just learned to walk and were always wanting to), and when we got to a path, an old grandmother was peeing on her granddaughter, a child of about 3 or 4 years old. The grandmother saw us and said to go pull her little sister, I said no, she's just going to walk. Then the little girl came over and slapped my child directly on the head and the grandmother laughed and said how can you hit your sister. I then slapped the little girl directly on that hand and the grandmother cursed and came over and hit me and said she would teach the child. How can I hit a child, the child's grandfather is also saying how can I hit a child. When the crowd got bigger, the grandmother pointed at me and cursed while pulling my child, so I just hit her hand and said, "Are you blind? Are you deaf? My child was hit on the head and cried, and you still beeped! Then more onlookers, I said the police, see how to deal with, they are still cursing, I just carry the child away. Completely do not feel that they are at fault, I'm alone with a child, walking a road can also hit this pair of old people, is also drunk.
