Could you share an hour a week with Naliaka?

I'm writing for my neighbor Naliaka, who's 73. Naliaka lives alone in Arusha, and lost a sister last year. The nearest family lives 500 kilometers away. Naliaka loves gardening, 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. Even a small gift gets used right away and I'll thank you myself.
