After a long time training a kid to learn how to use a toilet, my collegue showed up and said:
Collegue: "Jô I have good news and bad news. The good one is that finally your work paid off and Z. asked to do pi pi on the toilet."
Me: " yeahhhhh. Finally. The bad one?"
Collegue: " is that you forgot to teach her the notion of toilet. She made it. On the floor and It's waiting there for you to clean!"
