Men were stupid. Stupid, suicidal little creatures.
Toothless and his man had been flying across the great wide ocean, shooting over waves and marveling at its deep blues. His man had urged him upwards and they shot up through the clouds, higher and higher, wings whistling and pushing against the winds.
Then he jumped. It was a silly habit he'd picked up soon after he and Toothless had had their first real flight. Toothless hated it.
His little man plummeted quickly towards the ocean and Toothless dived to match him. He struggled, aimed and made himself cut through the air so that he could get farther down as fast as possible.
This time, much like many others, they survived just barefly, cutting it close as Toothless had finally reached the side of his man, who laughed at him and reached for the tough man skin hooked onto Toothless' back.
He'd jumped again the day before off the highest cliff on their nest island and Toothless had had to rush after him then, too.
And the day before that down a large, open cavern deep in the cracks of a rocky, jagged island they'd just discovered.
His man had jumped into clouds, off tall trees, down mountains and onto the backs of other dragons. He'd jumped into mouths and run through nests and played with their young and it always fell to Toothless to save him from whatever trouble he'd gotten himself into.
The other dragons' men certainly weren't anywhere near as crazy as Toothless'.
He wondered how he'd ever survived anything without him. He was stupid and crazy and he alway gave Toothless enough fish to make up for it afterwards. He bared his odd, blunt teeth at Toothless and rubbed him under the chin just where he liked it. He helped polish Toothless' scales, picked eels out of his baskets, gave him his own man skin and belonged to Toothless.
His man was a stupid shrew and Toothless loved him anyways.
