The school librarian called me on Tuesday afternoon. I was already on my way home for the day and I was surprised to receive a telephone call from the school. I decided to answer even though I was already gone for the day. The librarian told me that she found some kids smoking marijuana out back by the loading docks. I asked the librarian and she was 100% positive that the kids were using recreational marijuana. She explained that the scent was distinctive and she was absolutely positive. I turned my car around and headed back to the school. I was only a few miles away when the phone rang. I pulled into the parking lot by the office and I walked down to the library. The door was locked, so I stopped. The librarian came to the door. She had all three of the kids stuck inside of the library and she refused to release any of them until I arrived. I did not recognize any of the students from our school district. I got the names of each one of the students. One of the kids was a junior and another was a sophomore. I have no idea why they were hanging out at the middle school, but these kids were in a lot of trouble. I made each one of them call their parents and I did not release the kids until an adult came to pick them up and talk to me about the marijuana incident. We take drugs on the school campus very seriously. I could have called the police.
