Unwanted behaviour according to The I:

"I love trains, to meet new people, all those pleasant small talks, the feeling is always the same - desire to explore new people, places, cities. Help someone to pick up a heavy bag, give a compliment just to cheer someone.
There is another side to the story - to be there in the compartment in silence, listening to sounds of steel wheels on rails, take a nap in the seat, read a book or have a nice black coffee in the restaurant car. Contemplate and simply enjoy life and travel, enjoy exploring yourself."
