I remember ding dong ditching as a kid, but wish at that age I understood how annoying it really is. Mom and I were drinking tea and someone knocked really loud on our door. After opening it and seeing no one was there, I stood with the door slightly cracked and saw some girls running up the street. As I was playing piano they did it again, but this time I didn't bother answering. I sensed that they were going to come back a third time and decided that I needed to do something- lest they kept coming back the whole evening. I stood by the door, looking through the peep hole, waiting for them to come back. Alas, I see a girl quickly approaching my door, and as she reached to knock and run away, I knocked really loud from my side before she got a chance. She's an amateur, she wasn't expecting retaliation- she ran away screaming. I got her sooooooo good!
