Busted again............................naturally

I keep thinking that someday Sandy will learn that she can't get anything past us. This morning I got up with Mike. I was going to my ladies bible study and Mike was going to the food bank to get our weekly allotment of food. At 7:45 this morning (the time that Sandy is allowed to leave to catch her bus) I hear her trying very hard to walk quietly down the hall. I look up and she is about to walk out the door and see that she is walking out with sandals on her feet. It was far too cold for her to wear them to school and she did not ask if she could wear them. So I told her that she needed to turn her butt around and change into sneakers and that she is not allowed to wear sandals to school. She turns around, goes into her room for about 30 seconds and stomps out the door, yelling bye over her shoulder and slamming the door. I turn to Mike and say "She was not a happy camper about changing her shoes". He says "Oh well, she will get over it. I would have considered letting her wear them if she had asked and it was the last day of school". Since we can't trust Sandy to do as she is told I decided that I would take her sandals into our bedroom so she would have to ask before she can wear them. I search her room top to bottom and could not find her sandals. I figured she put them in her backpack. When she walked in the door this evening after school, I searched her backpack, but could not find the sandals. I asked her where her sandals were and she gets this "Oh crap I'm busted again" look on her face. She just gives me a blank look. Mike asks her if they are in her locker and she said yes. I asked her how they got there and she gave me another blank look. I said you took them to school after you were told not to, didn't you? She was honest enough to say yes. I told her to bring them home and that she was going to loose them. She was not too happy but right now she is lucky to even have shoes. I will not tolerate disobedience and lying.
