Chained to the wall

The girls and I met Mimi the other day to see a new Disney movie, Frozen  It was right near Sean's office, so afterward we stopped by to see him.  They love going through the circular door the most.  After meeting a few people along the way (and asking lots of questions), we got to daddy's office.  Maggie immediately go in daddy's spinning chair and started to pretend she was on the phone.  At one point she went to hand the phone to her sister.  As she handed it across the room, the cord did not quite reach.  Totally baffled, she said, I would give it to you, but Daddy has his phone chained to his desk.  I guess she has never seen a phone cord before!
