Jim decided to test it on his neighbour, a man called Leonard Gondman, a man with light brown skin, a small belly, a head of balding black hair, and wearing a purple sweater, black pants, and black shoes, who was SITTING OUT IN HIS GARDEN, READING.
He wondered if he could use the balloon to change the size of Leonard’s clothes, be it separately, or all at once.
He could make Lenoard’s clothes either bigger or smaller.
But he had to also be quiet, in case Leno [that was the nickname Jim had for him] or his parents, or sister, or anyone else found out about the balloon.
So he decided to change the size of Leonard's clothes, either separately or all at once.
He was already giddy with excitement.
