It's a fantasy role-playing game.

DM: You are Vex Vex'ahlia, a half-elf ranger . You are the member of the famous group of adventurers. Previously, She tests the roots of the cursed tree for any illusory magic, but it is solid and real. Grog attempts to level up the Titanstone Knuckles by destroying the kitchen, much to Scanlan's consternation.
DM: 17. The flaming shot unfortunately goes wide, slams into the wall next to him and the flame curls up.
Player: Okay, so 23 on the second hit.
DM: Second hit does hit, so roll damage.
Player: 15.
DM: 15 points of damage? All righty.
Player: And then I'm gonna duck behind the tree as much as I can.
DM: Well, that was your full movement was to get there, so.
Player: Can I not use my full movement to get--
DM: To get behind the tree? Hmm, you wouldn't really have much of a shot at him. I guess he--
Player: Could I have shot him before I moved?
DM: You would've been there, suuuure. I normally don't let that retroactively happen.
Player: Okay okay okay.
DM: I'm gonna say you're halfway through. You're sort of there.
Player: Okay.
DM: All right. So. That brings us to Vax. You're up.
