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

I'm writing for my neighbor Wunmi, who's 83. Wunmi lives alone in Lagos, and lost a spouse of many years last year. The nearest family lives 410 kilometers away. Wunmi loves gardening, 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. I never thought I'd be the one asking, and I'm grateful for every bit of support.
