At a bus stop in Santa Clara, a middle-aged man walked up to me to ask for a quarter. I didn’t have change, so I offered him a dollar instead. He thanked me, and walked away.
A few seconds later, he turned around and returned to thank me again. “I really don’t know how to say this… but thanks again… I just need it to make a phone call,” he said. “No problem!,” I assured him.
Walking a little further this time, he came back once more. “Really… I mean it… thank you!”
"Don’t worry about it!," I said to him again, running out of words to reassure him that it was okay.
Another few seconds later, he came back a third time to ask for the time. He thanked me again as he walked away — thankfully, for good this time.
I suspect he may have had a mild disorder, but then again, he may just have been the most gracious man alive.
