A weekly visit for Orhan, 77, who lives alone in Üsküdar

I'm writing for my neighbor Orhan, who's 77. Orhan lives alone in Üsküdar, and lost a lifelong friend last year. The nearest family lives several hours away. Orhan loves chess, and would enjoy someone to chat with. An hour a week, perhaps on Tuesday 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. Thank you so much.
