I'm a 15 year old who has sadly fallen in love with stage management, I've shadowed the Lion King Las Vegas stage management team 4 times, a SM from Phantom of The Opera Las Vegas, and the touring production of Mamma Mia. My favourite story is either getting to sit in the lobby with Kevin, a SM from the LKLV team, with all the Hyenas waiting for their cue to enter the house, OR, sitting in the booth with the SM from Phantom, and the pyro tech goes "Watch this, Dack," and turns a key, presses a button, and the stage lights up in fire, and he says, "boom, magic."
As a side note, I've taken what I learned at these productions and applied them to how I manage my high school's shows.
A more embarrassing story, I had an espresso before shadowing the SM of Phantom, and consequently, had to go pee about 10 minutes into the show. They had to ask the dance captain to take me down the elevator and show me where the bathroom was. Awkward.
