Passive aggression is telling your housemate that he takes too long in the shower by turning on all the hot water taps in the house at the 15 minute mark.
Passive aggression is doing all the dishes, but making a point of not doing your housemate’s favourite plastic yellow bowl which is plastered in hardened pools of last week’s chocolate ice-cream.
Passive aggression is insisting on only washing that bowl at the 15 minute mark of your housemate’s shower.
Passive aggression is taking your housemate’s disgusting kiddy bowl and placing it outside of his bedroom door, so that he trips over it when he stumbles out of bed at midday for his shower.
Passive aggression is taking your housemate’s festering ice-cream coated plastic bowl that represents everything that pisses you off about your housemate, and barging in on him at the 15 minute mark of his shower, ripping open the shower curtain and screaming, “WHEN YOU THINK THAT YOU’RE SUFFICIENTLY WASHED, WHY DON’T YOU WASH THIS?!!”…and then turning on all the hot taps in the house.
That’s all I have to say about passive aggression.
