A Word of Caution

"Goodnight, Luke," I say as I tuck him in bed, turn off the lights and head for the door. 

"Mommy," the little voice says, "be careful."

"Be careful of what sweetheart?" 

"Booby traps." 

"Okay," I respond with a confused look on my face. I have yet to encounter the said booby trap, but I'm waiting for it at every corner.
