He didn't quite make it

We went swimming at some friend's house tonight. Levi was standing outside the pool, with a strained look on his face.

Me: Levi, did you go poop in your suit?
Levi: Noooooo...
Me: [ checks Levi's suit and finds a few "treasures" in there ]
Me: Levi, you did go in you suit. Why didn't you tell me you had to go poop?
Levi: Well, I did tell-ded you, but you didn't obey me!
