Basically just anything I can while waiting for time to pass. I can’t get deeper into something, because there’s not enough time. Usually that ends up being walking back and forth and thinking, having a fake conversation in my head.

like when sitting in the train

I don’t consider that idle time, but a fun activity. I often take a train or bus nowhere. That means, as far as I can go and back. Or try to make my commute as long as possible. For example, I found nice connections allowing me to extend my commute from school from just 18km to 133km, and it’s only €0.90 more expensive.
