Companionship wanted: Josefa's chess and a cup of tea

I'm writing for my neighbor Josefa, who's 81. Josefa lives alone in San Diego, and lost a son last year. The nearest family lives 871 kilometers away. Josefa loves chess, 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.
