We come home from school and pull in the garage. He silently jumps out of the car, runs inside to toss his lunch bag on the counter and then without even a hidey-ho he disappears back outside.
Like he's running off to some important mission that needs accomplishing ASAP.
Sometimes I go outside and give a whistle.
"Yea mom?" he comes running.
Here boy, and I hand him food.
Which he stuffs in his mouth.
"Ok thanks!" and he runs off again until dinner time.
