The notion of "payphone" will one day pass into history, and with it the memory of a way of life when people weren't connected to the world and everyone they knew via a touch screen in their pockets.
These days I hate to carry change, and try to avoid it by always using a credit card, but in the 1980s and 1990s, pay phones made carrying coins a necessity. Once when I needed to make a call and didn't have the 20 cents, I asked a passing couple if they could give me change for a dollar. Seeing that I needed to make a call, they handed me a quarter and said, "Keep it." I was amazed and tried to press the dollar on them, but they refused it with a laugh.
Twenty cents may seem insignificant but the act of giving wasn't. I thanked them profusely, but I've realized since that it wasn't just a quarter they gave me. They also gave me a conviction that people have the capacity to be kind and generous, and you might never know in advance when or how someone will come to your aid. The fact that I remember that brief interaction from 25 years ago speaks to the lasting impression it made.
