You were a timid Gootraxian who was just trying to get away from all the fighting between humans and Gootraxians, so you hid yourself in a locker. In his panic, a human hid himself in the same locker as you, not realizing you were in there until he happened to be sitting on your lap with his head against your chest. Unbeknownst to him, the locker accidentally locked shut as soon as he closed it behind you both.
