Companionship wanted: Raquel's opera and a cup of tea

I'm writing for my neighbor Raquel, who's 83. Raquel lives alone in Porto Alegre, and lost a son last year. The nearest family lives several hours away. Raquel loves opera, 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. Even a small gift gets used right away and I'll thank you myself.
