Have you ever shown up to a new friend’s house and knocked on the wrong door? The last time this happened to me, I didn’t have any idea that the door I was knocking on might have been the wrong door. I parked (in what turned out to be the wrong driveway), strode up to the door and knocked. A man I had never seen hesitantly opened the door and we both stared at each other quizzically. He probably thought the stranger in front of him was about to sell him something or convince him to sign a petition. Meanwhile, I couldn’t figure out why this stranger was opening my friend’s door. Several seconds of silence passed before I awkwardly asked if this was my friend’s home. He kindly let me know that I wasn’t at the right house so I turned around and shuffled back to my car where I realized that my friend’s house was one door down. Oops.
