Usually see how many stinky farts I can rip and look at other people like they done it.
When I went on a residential I remember making every stupid noise I could make and see how long I got away with it.
I listen to a really long playlist.
I like watching the stars for others.
chat with the person next to you, judge how people slept in the vehicles, toilet break.
I prefer a train trip than a long bus, as I think, we can move or go to the toilette and go to other wagon to buy somethings for eating, like the water, or a sandwich etc. So it 's convenient .
When I'm not watching the scenery, I read a book.
