I am not a fan of April Fool’s Day, however I live in a house of tricksters and pranksters SO after a predictable, “You have something on your face” from my oldest son, I countered with, “The cinnamon rolls are gone.”
To which he replied, “WHAT?! Who ate them?”
Me: “April Fool’s!”
Gotcha. 
Good luck out there. 
The school teachers are probably glad it’s on a Sunday this year. Palm Sunday at that. One of my favorites. ~ Janean
