Folks who eat greasy food then push the button at the pedestrian crossing. Folks who stand directly in front of elevator doors as if they can't imagine that anyone else might be riding that elevator and want to get out, folks who try to board the train before others have alighted. Folks who cough in other folks' ears, folks who don't wash, folks who yell private conversations into cell phones in public places. Folks who stand and chat in the middle of busy city pavements, folks who walk out of shops without looking first, folks who shake their wet umbrellas on other folks. Folks who ride motorbikes loud enough to set off car alarms, folks who play the doof doof in their cars loud enough to rattle windows. Folks who talk over the top of other folks, roll their eyes or simply don't listen to other folks. Folks who pick one insignificant point from a conversation to carp about and ignore the essential. Folks who sit on a crowded tram while the frail stand.
I could go on.
Come the revolution we are going to need a very large wall for all the folks who are going to first against it.
