What fucked up thing did you do as a kid?

This story is a bit long so bear with me:

I was on vacation in the motherland with my family and we were staying at a high rise hotel in the capital. My parents and sister were in the other room watching TV, and so I decided to open the hotel window to get some fresh air.

After getting bored of that, I took the notepad and pen that hotels usually supply and I started writing all the bad words that I knew in the local language. I then turned these pieces of paper into paper airplanes and threw them from the window. Pretty harmless right? But wait.....

After getting bored of my profanity paper airplanes, I looked to the vase on the table that had some fake plants in it with little decorative rocks at the bottom, and thought “ah yes these would be perfect to drop from the window.” So being the dumb little kid that I was, I dropped a few of these little rocks from our window and tried to keep my eye on them as they flew down towards the ground. Keep in mind we were like 20+ stories up so those suckers picked up some serious speed as the plummeted towards the ground.

After dropping a few of the rocks I got bored and closed the window and joined my family in the other room. Fast forward to later that evening as we were walking through the lobby to go to dinner, some hotel security guards stopped my parents and asked them if they had been dropping anything out the windows. I didn’t speak the local language so my parents asked me if I had dropped anything from the window, and with a straight face I responded “no not me”. My parents relayed that back to the security guards and they apologized for bothering us and off to dinner we went.

Turns out my window was situated over the valet parking lot and my little rocks had caused some damage to cars parked below. I kept this secret to myself for like 8 years before I finally told my parents and we were all able to have a good laugh about it, but damn was I a cynical little liar back then.

TLDR: Dropped little rocks from 20th+ story hotel room window and caused some damage to cars parked below. I then lied with a straight face when confronted by hotel security as my family was going out to dinner.
