Citizen of the World

This morning, as per usual, I woke my 10-yr old son up at the unearthly hour of 7.20am. I put the lights on & was greeted by a groan of "Turn the light off!"
"Is there a word beginning with P in that sentence?" I asked (this is mum-speak for: You need to say please!)
Immediately came the answer: "Por favor"
Quick thinking, in Spanish, at that time in the morning...........I'm impressed!
