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!
