I never got that, isn't it the parent's property?
In 10th grade my spanish teacher took my video game magazine because I was reading it instead of doing classwork. My mother walked in and told the teacher that she understood, and she'll make sure I don't bring video game magazines to school again. She refused to return the magazine. At that point my mom made it clear that since she paid for it, it was her property and if she didn't return it immediately she would be going to the police.
Then in the car my mom smacked me with said magazine and told me to never put her in that situation again.
