Sam was used to being taller than the majority of people. He was used to looking down and not up when carrying on a conversation. Particularly a conversation with a child. He'd watched as Maxine got up to board the bus and then suddenly he felt as if she were growing taller. Though if she were growing taller, everyone else around them and even the buildings were growing taller too.
Sam fell forward and put his hands on the ground. It was then that he realized that those-those were definitely not hands. He stared at the fur paws and vaguely wondered why he suddenly had a strong desire to see a tennis ball. Or more importantly, to find a tennis ball to chase.
He looked up to say something as Maxine gasped. Instead, all that came out was "Woof!"
