The Game Master

You hear a 'ding'. A smile grows slowly on your face. You are pretty confident what it means. "Welcome. Thanks for visiting. Please take your time looking around and have fun." The panels then folds away into the wall and you move on.
"How obvious." You think aloud. Titch nods at you and climbs onto your head. You pat him and he begins squeaking at you. You chuckle to yourself and stroll along. The door locks behind you, making you feel uncomfortable. The walls are mirrors. Its a long corridor leading in one direction. You check your surroundings anyway. You see a glimpse of someone, but pass it off as your imagination. The more you walk, though, the more frequent these glimses are. As you reach the end, cackling can be heard. An image of the Game Master appears in the wall. The quickly shoot yours eyes around the room looking for a projector or the actual person, but only the man in the wall can be seen.
He begins to talk, " Hello child. You are intruding. Get out."
"I-I'm just here f-for a.." You begin.
"Get Out!" He yells.
How do you respond?
