Why don't old people make friends with young people?
Some old people may feel that there is a generation gap between them and young people. Or some old people are not energetic and think young people are too noisy. However, some older people are more conservative and may be wary of outsiders. Some old people feel that associating with young people lowers their status. Young people know and understand these situations properly. And try to communicate with the elderly in a more appropriate and polite way.
