Here's a place to post your thanks to a stranger who helped you or touched your life in a special way, someone you're not able to thank in person.
My thanks goes to the guy who shared a taxi with me after BART broke down - this was 20+ years ago, before cell phones - when I was frantically trying to get to the closing on our first house. I had about 30 minutes to get from Oakland to North Berkeley, so a bus was out of the question; after explaining my situation and the fact that I didn't have money for a cab, he allowed me to share his. He got me to the closing in time and wouldn't accept a check or any kind of payment.
Thank you for your kindness, which I've held in my heart all these years.
