A weekly visit for Randall, 78, who lives alone in London

I'm writing for my neighbor Randall, who's 78. Randall lives alone in London, and lost a lifelong friend last year. The nearest family lives a long flight away. Randall loves local history, and would enjoy someone to chat with. An hour a week, perhaps on Monday 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.
