DD met a new friend (age 5) at a play structure. They decided to play tag.

NF: You can't tag me here.
DD: Why not?
NF: This is a safe zone.
DD: We are playing the ORIGINAL game of tag.
NF: What?
DD: Original, meaning no modifications or special rules.
NF: What?
DD: I can tag you anywhere since we didn't agree to having a safe zone prior to starting the game.
NF: I don't understand you.
DD: Is English not your first language?
