We (as in Tom and I) shave Tom's head every few months or so. Tom always begins the process by wetting and conditioning his hair (which keeps it from catching in the trimmer quite as often) and then shaving the majority of his head. At that point I step in and finish things up, making sure he hasn't missed any spots and cleaning up his hairline and sideburns. When Tom's head has returned to a state of baldness, I walk away and let him sweep up the piles of hair that have accumulated around the lawn chair. Our step-by-step process has been perfected over the years, and we rarely deviate from it.
Which is why I was shocked when I stepped out onto the back porch, ready to begin my part of process, and found Hallie shaving Tom's head.
Bravery = allowing your 3-year-old daughter to shave your head.
