As much as I hate to say it, we do. A lot, unfortunately.

And dragons don't talk where I'm from. Toothless is pretty good at getting across what he wants to say anyways, though, and I'm not too shabby at figuring it out myself.

We make it work. Don't we bud? Don't we? Yes we do...

[Hiccup starts scratching behind Toothless's earflaps, and the dragon starts thumping his back leg before turning and licking him.]

Ah, yep. there's the slobber. Wonderful. That still doesn't wash out, y'know.

[The mischievious look on Toothless' face says yes, yes he does know.]
