Friendly visitor needed for a 79-year-old neighbor in New York

I'm writing for my neighbor Cristina, who's 79. Cristina lives alone in New York, and lost a spouse of many years last year. The nearest family lives several hours away. Cristina loves chess, and would enjoy someone to chat with. An hour a week, perhaps on Friday 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. Glad we found this place.
