Xray vision?

I am standing at one end of the house, ironing clothing that has been patiently waiting to be ironed for 6 weeks. Dave is at the other end, paying bills. We are having a quiet morning of chores (welcome to vacation!). Then Dave walks through the house toward the kitchen, I smile at him, and the baby kicks! Pow! It's like the baby has Xray vision. Here comes Dad!
