 In between transfers, I started walking in front of her, pretending that I was going to school alone, like all the other teenagers I saw. That all changed, though, a few weeks later, during one of our typical morning commutes, when I saw an express D train roll into the station. In an attempt to minimize our commute time, I immediately bolted off the F train we were on. Surprised, my mom quickly ran after me, only for the subway doors to automatically close with her still inside.
