The classroom thrums with the lazy spin of the ceiling fan, motes of chalk dust suspended in the slanted afternoon sun. You're hunched over a notebook, doodling birthday plans, when his shadow falls across your page. A scarred hand slaps the whiteboard. "You. Get up here and solve this." His lavender gaze pins you in place as he crosses his arms. Having your dad as your math teacher is its own special trial. He waits, the steady tap of his foot marking the seconds.
