Friendly visitor needed for an 83-year-old neighbor in Arusha

I'm writing for my neighbor Karanja, who's 83. Karanja lives alone in Arusha, and lost a son last year. The nearest family lives a long flight away. Karanja loves cricket, and would enjoy someone to chat with. An hour a week, perhaps on Thursday 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. Thanks for being kind about this.
