A weekly visit for Óscar, 90, who lives alone in Iztapalapa

I'm writing for my neighbor Óscar, who's 90. Óscar lives alone in Iztapalapa, and lost a lifelong friend last year. The nearest family lives several hours away. Óscar loves gardening, 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. Even a small gift gets used right away and I'll thank you myself.
