A movie moment

In movies and stories it often seems like the writer doesn't know how to make two people meet, so it just happens casually at a restaurant or train station. But all of us normal humans know that doesn't happen in real life. This time it did.
I was out having lunch with a friend from school at a little coffee shop. We had finished our sandwiches and were looking at the pastries in the cabinet behind me. Between my friend and the pastries, there was an old man sitting directly in the way. She finally started to feel awkward about staring past him and explained to him that we were looking at the sweets not him. This led to a nice little conversation about what we wanted to eat, where we are from (the accent gives us away), and what we are studying at University of Glasgow. Turns out that we talked for about thirty minutes and by the end of it he had decided to take us under his wing. He gave us his phone number in case we had any problems during our time here, and he gave us the email of a friend of his who teaches at CU Boulder for when we get back to Colorado. Then as we were about to leave he told us he wanted to show us the best ice cream on the block. We followed him as he teetered down the street a ways with his cane. Once we reached the "best ice cream spot in town," he asked us when we would be free to meet him. We decided to meet the next afternoon for ice cream. When we showed up the following day, he was waiting for us. We sat for about an hour and chatted. He paid for our ice cream and gave us nice pens from his company. He has lived in Glasgow for almost all of his life with the exception of the war and a few months that he lived in California. He told us so much about the city and country that we would not have known about otherwise. And by the end of the ice cream he introduced us to a friend of his that walked in as his new American granddaughters. I am not quite sure how it happened, but I gained a Scottish grandfather just by eating a sandwich and having a sweet tooth.
