“I remember the big gaping hole left by my dad’s absence in the months following the accident. He’d been the one who went to my parent-teacher conferences, the one who taught me mnemonics to memorize the Great Lakes and the Earth’s atmospheres. Whenever I did something silly, my dad always made me feel better by telling me a story from the firehouse about someone who had done something even sillier. Sometimes you don’t realize all the things a person does for you until they aren’t there to do them anymore.”
