Fuck you, Stephen King.
Go ahead, pretend you don't write piles and piles of shit. You do. You know it. And when you're afraid you're going to write a pile of shit, you don't even use your REAL NAME! You use a pseudonym.
An adverb is simply something that describes a verb. I yelled angrily, then crept stealthily before I ran quickly to the store! It was a grimly scene.
"(It's like explaining a joke — if you need to tell us something happened in a grimly or someone spoke grimly, then it's not really that grim.)" - Charlie Jane Anders, Io9.com
But you know what, adverbs, like everything in life, are perfectly fine in moderation. Thank you.
