I was sitting with my co-rover Yitzchok in the ancient synagogue early morning saying Psalms. Suddenly, a couple enters. The man looks around, and approaches me. I look up with a smile and ask if there is anything I can do for him. In English, he tells me that he wants to recite the Amidah (silent prayer). I lend him my prayerbook. He spends a few minutes praying, kisses the book and walks out.
A few minutes later, they return with another couple. He introduces us to their friends with whom they are on a cruise, and explains that he had originally come because he needed a favor from G‑d. Their fellow traveler had lost her wallet which contained some very important documents. No sooner had he finished praying when he got a telephone call from someone who had found the wallet, and now they all came back to say thank you to G‑d.
