Mia has had her room taped off for over a month. She recently added the orange tape, but the sign has warned people to stay out for quite some time. It reads, 

Knock First!
You need an I.D. to come into Mia's room and she needs to accept it and says you can come in before you come in.

Yes, the orange tape is right in the middle of the door, requiring Mia (and anyone else) to duck in order to enter or leave the room.

Such a fun kid.
