Why So Grump

This is my friend Granite; he's a grumpy horse.
He's a nice guy, just hardly ever smiles, like, ever.

It seems even my attempts to make him smile proves futile, but at least he looked happy for a second.
In the end I decided if you can't beat 'em, join 'em. I admitted defeat, so now we're grumpy together!
