I was wandering around Dumbarton Road trying to find the post office that Google maps told me was close when I decided to get some help and ask a nice looking old man for directions. He told me that the post office I was looking for was closed, and gave me some directions to a different one. It turns out we were walking in the same direction for a bit and smiled and said, "It's not every day I get to walk next to a beautiful lass." I said, "It's me that's lucky, cause I get to walk next to a handsome gent." The man chuckled and, as he turned to go into a store, said that I needed to see an optometrist. I replied, "That's where you're wrong, you're assuming that I judge beauty with my eyes."
I wish I could say that I actually said that last sentence, but I only thought of it after the man had walked into the store. All day I wondered how his day might have been brightened by the words if I had uttered them in time. It goes taught me a lesson though: I will always regret kind words left unsaid.
