Murphy's Law of moms and bathrooms

If you attempt to use it... there will be a crisis.

Case in point: this morning Ian comes running back down the stairs to me after having gone to play fireman in his room.

He's so very sad - red in the face with tears streaming:
"Mommy, it turns out I'm not a fireman, I'm just a plain old Ian. I stubbed my toe!"

Poor little guy. Apparently firemen do not stub toes.
