Yes, I may be jumping the bandwagon of "piss off" threads, but I'm alright with that.
INTJ's, what pisses you off? What irks you?
Everyone else, what do you say upsets the INTJ?
Everything. I can piss and moan under any circumstance; but it's this that leads to improvement.
Hmmmm, more specific.... When people can't follow simple cause and effect.
