Sarah can tie a really good knot

All of my kids are in their rooms for "rest" time and I hear this horrible thud sound coming down the hallway. My first thought is who is making that noise and when I find who they are going to be in trouble if they wake up the twins. I wander down the hall and don't see anyone but I hear Sarah whimpering. I walk into her room and find Sarah tied up. She said she was trying to hop on one foot. My first thought is why would you do this, but my second thought was wow that was a great knot you tied. Needless to say she had done such a good job with the knot that I had to cut her free.
