I put my bag down on the ground to avoid taking up any extra space.

I wear headphones so others dont hear my videos/ music/ podcasts/ calls

I mind my business and don’t stare at others.

I dont do anything that might gross out other people like picking my nose, picking my ass, scratching my balls or touching other people inappropriately.

Apparently this is a routine specific to me since the majority of people on public transport dont do these things.
