Being completely unaware of anyone else:
- Standing in doorways, using your phone or having a conversation
- Talking loudly when inappropriate, when I’m in pain at the doctors, I don’t want to hear about your roses
- leaving your shopping trolley blocking the aisle sideways in the supermarket while looking for your stuff
- driving down the middle of the road so everyone else has to pull over, when there’s plenty of room for two cars to pass
- stopping in the middle of the road without indicating, while: looking for your destination, or having a conversation, or deciding what day it is
- riding your delivery bike down the footpath at high speed weaving between pedestrians
As Jean-Paul Sartre said, “Hell is other people”.
