The scale was horrific. Robbie was the size of an insect. He could see giants moving across the gym floor, but from his perspective all he could really see were shoes. He couldn't tell, unless they had pom socks whether the shoes belonged to girls or boys. He'd already deduced that women seeing his nakedness had a profoundly negative effect on his height. So he needed to avoid being seen by girls, and he needed to be seen by guys, if he wanted to grow big again.
A giant ant skittered along the base board. It didn't notice or didn't care about him. But the mammoth size of the creature made him feel even more vulnerable. There was a thunderous crash, and the ground reverberated beneath him. Someone had set a gym bag next to the bleachers. It had to be 100 stories tall, but fortunately for little Robbie, it had fallen upside down. It was open so the clothing spilled out. A voice thundered in the distance, "THANKS!"
Footsteps sounded closer, as the bags owner ran to retrieve its contents. Robbie ran too, and dove into a white canvass cloth, just as the giant hand grabbed and thrust it into the dark confines of the bag. This time the bag was zipped shut. Robbie collapsed into the clothing and waited to see who would open the bag. He couldn't smell male or female scent, just the overpowering smell of fabric softener, and the new smell of plastic. Robbie concluded that the new sports bag contained clean clothing. Whether the bag belonged to male or female, he'd just have to wait to see. After his strenuous runs as a flea sized man, Robbie was exhausted and fell asleep.
He was awakened by a violent rocking, as Robbie opened his eyes he saw he was rocking back and forth on the white cotton canvass. He had been faced down, as he struggled to rise, he could see that the canvass was racing upward passed giant lockers. As he turned to face the growing shadow overhead, he recognized human butt cheeks. He was trapped in someone's underwear. He was pressed against the backside flesh before he could venture toward the wearer's front to see whether he was trapped in a boy's or girl's shorts. The principal smell was the antiseptic soap used in both shower rooms, and the flowery smell of fabric softner in the cotton briefs. He started to crawl toward the front of the briefs.
