I told my sister that if she didn't go the hell to sleep, one-armed zombies from the moon were going to come down to earth and kill her. The zombies I made up did not have eyelashes, and that was apparently the thing that caused her the most distress and continues to cause her distress into her adult life, as she reminds me whenever she sees me.

Also, I squirted Windex into another sister's eyes but it was on accident. I really liked the blue color and just wanted to pull on the nozzle, and she happened to be sitting right in front of it.
