I went to school today by walking from downtown (I live in Chicago), and on the way I walked through the "Greek Town" neighborhood. It was about 10:30 or so in the morning, and as I walked, I noticed a penny on the ground. As is my habit, I pocketed it (I've learned this practice as a good way to save up money....I collect all the coins I find and save all the change I get from purchases, and after about a year, I can exchange it for a lot of money, usually $80 or so).
A gruff man was standing outside one of the Greek Town restaurants, smoking a cigarette, probably on a work break. He saw me pick up the penny and said, "Good luck, buddy!"
I'm not sure why, but that incident brightened my day!
