I'M SORRY I'M LATE. MAY I COME IN?
?
STAY IN YOUR SEAT
?
KEEP UP THE GOOD WORKS
?
MAY I GO TO RESTROOM?
?
ZIP YOUR LIPS
?
DON'T MAKE NOISE
?
KEEP YOUR VOICE DOWN
?
CAN I TALK TO YOU FOR A SECOND?
?
CAN I ASK A QUESTION?
?
LINE UP
?
MAY I DRINK WATER?
?
TURN ON THE LIGHTS
?
TURN OFF THE LIGHTS
?
HANDS UP
?
I DON'T GET IT
