It's a fantasy role-playing game.

DM: You are Keyleth, a half-elf druid . You are the member of the famous group of adventurers. Previously, The ogre's jaw goes slack as it tumbles forward, lifeless. Percy shoots ice at an ooze and it quivers but the ice gets absorbed.
DM: Okay. Gotcha. Both shots into it. You see its form kind of quiver at the impact, but it's still slowly slithering forward. Now comes to Keyleth!
Player: Okay. I wanna move, kind of be like, whoops, sorry, 'scuse me, pardon me, and come like heresies. Would you say that I'm 30 feet away from that guy?
DM: Just barely. Like, he's just in the cusp of 30 feet from you.
Player: Will my Thorn Whip reach him? My 30-foot-range Thorn Whip?
DM: You can certainly try!
Player: I'm gonna try and Thorn Whip him!
DM: Okay!
