Washing cars

"Mom, I need a paper towel!" I hear Kyle calling from his bedroom during quiet time. So, I take him a paper towel...and feel the wet spot on his comforter. "Kyle what happened? Why is your bed all wet?". "I'm washing cars mom". "With what?" I wonder and say out loud at the same time. "I just washing cars". Ah yes, the milk cup I gave him with just a little bit of milk left in it; but that's a leak free sippy cup...hmmm. "Kyle, did you unscrew the lid and pour your milk out on the bed?". "Ah hu, I washed No Stall. Can I have another paper towel?"
