Could you share an hour a week with Zaid?

I'm writing for my neighbor Zaid, who's 78. Zaid lives alone in Cairo, and lost a sister last year. The nearest family lives on the other side of the country. Zaid loves gardening, and would enjoy someone to chat with. An hour a week, perhaps on Saturday 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. Please ask me anything in the questions section. I'll answer honestly and quickly.
