I've done too many stupid things to list. Really, we'd be here all day listening to my bad life choices as a child, but the only one that I really feel like sharing wasn't entirely my fault.
When I was about 5, I suddenly, in the space of a few minutes it seemed, developed a rash that wouldn't fade when pressed with a glass, so my mother thought it was meningitis. She rushed me to hospital, because I couldn't tell her what was wrong, and we waited for a few minutes before a doctor rushed us into another room to check up on me- since, you know, meningitis is a huge deal and all.
He looked at my rash, which was big, red, and blotchy all over my face, and burst out laughing. He took a damp cloth, and simply wiped it away. Turns out in the few minutes before my rash had magically appeared, I had been blowing through the straw in my juice cup and it had sprayed back in my face. Being a messy little child, I didn't notice/wipe it away, so it had dried onto my skin looking like I was suffering from some tropical disease. The nurses were panicking over black current juice.
We were laughed out of the hospital, and my mother was too ashamed to show her face in the area again. 8D
