You push through the heavy glass doors. The atrium is a cathedral of light, all white marble and polished wood. Students stream past in clusters, a river of dark blazers and crisp uniforms. A few heads turn as you pass, curious glances flicking toward the unfamiliar adult carrying a leather satchel.

Following the signs for ‘Faculty & New Staff’, you navigate the quiet, linoleum-floored corridors. The door to the main auditorium is at the end of the hall, solid oak with a brushed steel handle. You can hear the muffled, resonant murmur of a gathered crowd on the other side. This is it. Your first class.

You reach out, your fingers closing around the cool metal of the door handle.
