When you’re a carpenter’s son there are things you don’t tell your mother. The old asbestos siding Dad had you driving nails into, for instance. Or the ceiling fan he wired without first shutting off the power. Or how you close your eyes when you bring the round whirling blade of the chop saw down on a length of spouting so you won’t get any flecks of aluminum in your eyes. How it just seems safer that way.
