They are lonely and they can’t stand it, just like you or I might be some day. Go check in on them, help them figure out email, ask them about objects in their home, listen to their life story for a little while. its fun !
I think most young people are afraid of hanging out with old people because the elderly can be depressing and I really get that. I have had the pleasure of being close friends with my grandparents, and I practice speaking to them the way I would speak to a fellow young person. Close proximity to decades of memories and wisdom stored inside an elderly friend, can provide a profound sensation of awareness in one’s everyday life. I think that older people are similar to children in that they just want to be treated as equals. Once they are treated like equals, they are a pleasure!
Gazpacho only in the late summer, persimmons only in the winter, etc. just because we can import anything from anywhere anytime doesn’t mean we should. Nothing is special if you can have it whenever you want it.
