In high school, my favorite class was AP Calculus. During class, our teacher peppered his lectures with humorous examples. One day he asked us, “If a boy and a girl are interested in each other and each moves towards the other by dividing the distance in half each time, will they ever touch?” At night and on weekends, I sat in front of the most impossible problem sets, the blank page of lined loose-leaf sitting there under the glow of my desk lamp, taunting me, egging on my growing confusion and frustration.
