It's a fantasy role-playing game.

DM: You are Pike Trickfoot, a gnome cleric . You are the member of the famous group of adventurers. Previously, Keyleth, angry and frustrated at the whole situation, drops her form, channels her rage, and unleashes a Fire Storm at Kevdak, Greenbeard, and several of the herd members nearby. Vax watches on in awe as the entire square is ignited in her flames of fury, the rogue quietly and quickly falling a little deeper in love with her.
DM: The Command move means on their next turn they attack each other. Doesn't mean that they're charmed or dominated.
Player: But how many feet did I move, how many feet am I able to move anyway?
DM: That would've been ten feet, you can move 15 more.
Player: Okay, I can move 15 more anyway.
DM: Yeah. But you will take two attacks of opportunity if you move out of range of these two.
Player: But wouldn't that be included in the attacks that I just took? If I can move 15 total?
DM: You can move 25 total because of your tiny feet. You moved ten, you have 15 more feet you can move.
