It's a fantasy role-playing game.

DM: You are Vax Vax'ildan, a half-elf rogue . You are the member of the famous group of adventurers. Previously, Three locks' scratchings translate to the Common equivalent of 'open me', one of the locks' scratchings warns the party not to open it. you discovers that the lock saying 'No' is trapped, and the ones saying 'Yes' aren't.
DM: In order to sneak attack a creature, you have to have an ally adjacent to the enemy, not to you. The idea is, they're being harried by two different points and can't form a good defense
Player: Okay, all right. Then I'm going to use Disengage, I'm going to step five feet back. I'm going to use one action to click my Boots of Haste. And then can I attack, because the boots are on, after that? Then I'll throw a dagger at him.
DM: Okay.
Player: That is a 24.
DM: 24 does hit.
Player: All right. 11 from the Keen Dagger.
DM: All right. Cool. All right. We have now officially, as of this moment, entered combat. You technically would be next in the initiative round at this point, but you're holding your action until-- what are you holding your action until?
Player: I was only going to do that if you told me that I could move around him, now that I know that I can't--
DM: All right, you did that, okay. Okay, never mind. Gotcha. All right, cool. So that will be, in theory, the first opening to the battle. Now we start the initiative order. All right. So now we're starting off. Vex, you're up first.
