Jeremiah ran for his house as fast as his growing legs would let him.
Once he got outside his house, he grabbed his keys, unlocked trhe door, and got inside, bumping his head on the doorframe as he did so. Since his teenage years, and an early growth spurt, Jeremiah had always been used to being a moderately big guy, just over 6'2". While not freakishly tall, he could reasonably assume that he would be among the bigger guys in most situations.
The doorframe was tall, so bumping his forehead on his way in meant he was standing at least at seven and a half feet!
Jeremiah mangaed to squeeze himself into his living room, and sit on the carpet. His already split clothes soon reduced themselves to rags, and his feet had grown free of his boots and socks before he'd opened the door.
Jeremiah was reduced to his tight white heart-patterned boxers.
Jeremiah sat and wriggled his toes.
