it's a one way street, because i said so

i never really expect the world to go according to my plan. that's one of the differences between cody and me. he totally does.
today he decided that our street should be a one way street. so he had me help him make a wood sign and pound it into the grass, next to the road. then he took a magic marker and wrote
ONE WAY
on it. actually, i think he wrote YAW ENO
anyway, then he sat on a rock and waited for cars to come. the first couple came the way he wanted......
and then one came...... THE WRONG WAY.
he was devastated.
his thinking just blows me away.
