Friendly visitor needed for a 76-year-old neighbor in Campinas

I'm writing for my neighbor Vinícius, who's 76. Vinícius lives alone in Campinas, and lost a son last year. The nearest family lives on the other side of the country. Vinícius loves local history, 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. Whatever you can give, even just sharing this page, means a lot.
