"I...just..." Carter fumbled his words and Frank's hat, almost embarrassed by the statement. People didn't thank him so emphatically very often. Sure, he got scolded plenty, and maybe there was a brief bit of praise when he did something really right, but he'd never been so outright helpful.

"It's nothing. Just doing a soldier's duty, y'know?" he managed awkwardly as he knelt again to stuff the second hat with snow. "It's not a big deal. I'm just used to this sort of thing." When he tied the second hat to Frank's arm he did it with a bit more flourish and an eager smile, even making the knot look prettier just so he'd have done the best job he could.
