Ok, I remembered one from my past that was totally not my doing, but alas...
I was in college, but back for summer break. Guess I was probably 19 or 20. My youngest brother was playing baseball and I was taking video of his at bats. He would have been about 9 or so, so 40 year old me now knows that this is a waste of time.
My sister and her friend are also at the game. They would be about 14 or so. All of a sudden, out of the blue, my sister's friend stands up, points to me, and yells, "STAY AWAY FROM ME, YOU PEDOPHILE!"
Yeah, lots of looks at the guy with a video camera at a kids sporting event.
My sister was horrified, and years later, her friend eventually apologized after she realized the potential implications of what she had yelled.
