Friendly visitor needed for an 87-year-old neighbor in Johannesburg

I'm writing for my neighbor Tracey, who's 87. Tracey lives alone in Johannesburg, and lost a sister last year. The nearest family lives a long flight away. Tracey loves baking, 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.
