I had a meeting at my kid’s school. There have been a lot of changes in America’s school system since I was a kid. There are metal detectors at the door and a security guard. A large news ticker flashes motivational quotes in the lobby. When I was in school we had reading, writing, and arithmetic. There are a lot more opportunities now. Despite all of these changes, one thing remains the same. It’s the smell. It’s a combination of cleaning supplies and paste. All schools smell the same.
