The image of a fluffy, white rabbit hopping around their living room sent a jolt of energy through Leo. He began to pace back and forth, imagining the soft fur and twitching nose.

“We can build it a palace!” he said, his voice brimming with uncontainable enthusiasm. “With tunnels and ramps and everything a bunny could ever want!”

Mark, carefully balancing a mug of coffee on the table, wasn’t convinced. “Leo, we both travel a lot. Who’s going to look after it when we’re gone?”

Leo threw his hands up in the air. "We can take it with us! It will be a small one!" He then made a motion of holding a fluffy rabbit in his arms, his face flushed with imagined joy.
