A weekly visit for Chalerm, 78, who lives alone in Bangkok

I'm writing for my neighbor Chalerm, who's 78. Chalerm lives alone in Bangkok, and lost a spouse of many years last year. The nearest family lives 267 kilometers away. Chalerm loves crossword puzzles, and would enjoy someone to chat with. An hour a week, perhaps on Monday afternoon, would mean the world. We can also arrange a phone call if you can't visit in person. All visitors will be introduced by me and I'll be there at the first meeting. I'll share references and, if you'd like, a short orientation from the local befriending charity. No special skills are needed - just kindness and patience. Thank you so much.
