Red Wrist

One day, I was sitting at my desk, writing out some pranks. Then I thought of a great one and wrote it down.
(BIG MISTAKE AS YOU WILL FIND OUT LATER)
I squirted mountains of tomato ketchup up my wrist, and started screaming for my Mum. She came running down, and then I screamed with pretend pain, and she wiped the blood off, and bundled me off to bed.

A few days later, when I was pretending to be better, Mum was clearing out my desk. She found my prank, and shook me. I laughed at my own danger!
