One thing you must learn about a prankster is they are extremely paranoid. Especially on April Fool's Day.
We had such a great plan to tin foil her bedroom. We know the code to her garage (security is TIGHT at her place!), but she foiled US in her state of paranoia and locked the garage door into the house. Frustrated, we made do with tin foiling anything we could in the garage
But then, Miss Paranoid came home early and caught us in the act!
Oh, next year, girl...I cannot wait to get you good!
