Could you share an hour a week with Cameron?

I'm writing for my neighbor Cameron, who's 77. Cameron lives alone in San Francisco, and lost a spouse of many years last year. The nearest family lives 217 kilometers away. Cameron loves chess, and would enjoy someone to chat with. An hour a week, perhaps on Saturday 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. I never thought I'd be the one asking, and I'm grateful for every bit of support.
