Snow
...
He didn't notice them at first; he was engrossed with the dry, crackling leaf that was fluttering across his path. His tail twitched as he watched it, wanting desperately to leap out snag it with his claws, but he knew what his mentor would say about such kit-like behavior.
And then he felt it, a sudden wetness on the tip of his nose. He blinked, startled, and batted at his muzzle. Another drip of cold moisture touched his paw. He whirled around, wondering what was going on.
The whole sky was filled with them, small white flakes that swirled and danced in the wind. He stared, wide-eyed, and then tentatively stuck out a paw again. The sharp frostiness was no longer unpleasant; in fact, it was almost exhilarating. "It's snow," Leopardfoot purred in amusement at the bewildered look on his face. Snow. Snow. So this was what it looked like. He lifted his paw again, stretching it out further. He watched the snow around it for a while, until he could stand it no longer. Letting out a purr of delight, he launched himself into the air, batting at flakes and falling into the crisp, thin snow blanket that covered the ground. It was exciting. It was thrilling. It was fun.
But then –
"What are you doing?"
He looked up quickly – guiltily - as his mentor hurried towards him. Thistleclaw seemed unfazed by the snowfall around him. On the contrary, he seemed severely annoyed. "Are you an apprentice or a kit?" he hissed as his came closer, "Thrushpelt's leading a hunting patrol and I told him you'd go. Why? Because I expected you to care about the hunger that leaf-bare brings. I did not expect you to be playing while your Clan starves!"
Tigerpaw flinched away from his mentor's harsh tone, all happiness gone. He ducked his head and murmured, "Yes, Thistleclaw," before hurrying towards the gorse tunnel to wait for Thrushpelt. The flakes were still twirling tantalizingly in the air, but he ignored them. He had to be as good a warrior as Thistleclaw insisted. There was no time for snow.
A/N: I had to write this, after rereading the bit in The Darkest Hour when Firestar wonders whether Tigerclaw ever played in the snow like his son did.
