I decided what toy I wanted to bring to school for show and tell. My mom helped me hide it inside of two paper grocery sacks, keeping my item secret until its unveiling.
When it was my turn, I walked to the front of the room and faced the other twenty first-graders. In one movement, I ripped the bags apart and aimed my black plastic assault rifle toward my classmates. The trigger activating its "realistic" bullet sound effects, I waved the large gun left and right, spraying the room and its occupants with imaginary bullets as my teacher looked on, unflinching.
That's how old I am.
