My neighbor is 84 and lost his wife last year. He has no kids and I noticed he stopped cooking and barely turned his lights on. He was just fading away. So now, every single night when I cook dinner for my family, I make an extra plate and walk it over. We sit on his porch for 20 minutes and just talk. He told me yesterday that our little chats are the only reason he gets out of bed. It costs me nothing but a little food and time, but it means the world to him.
