I was at a school to give a talk to a group of children and noticed this.

The windows were covered with children's drawings and works of art too: you could barely see the outside world. There were things made of newspaper and string hanging down from the ceiling and glittery paper plates as far as the eye could see.

Over the years, I've learned that teachers habitually attach things to walls at jaunty angles to give rooms some kind of dynamic that squared-up attachments just can't offer. I like how the children's project has upstaged the professor's years of service to the sunday school, but I immediately felt like I should at least do something to correct this for the sake of his legacy. Maybe I could lower the poster just a few millimetres if I stood on a chair? Just then, the doors opened and the children streamed in and – once again – the professor was (momentarily) forgotten.
