Point Taken
This is about as passive-aggressive as anyone can get. This person took the time to make this long, elaborate note just to inform their inconsiderate neighbor how annoying their new speakers are. The length and thought behind this note make it hard to ignore, and the only question that remains is whether this self-centered neighbor even understood this passive-aggressive note or whether they think this is a genuine compliment on their amazing new speakers.
While it’s hard to miss the sarcastic tone as you go on reading line after line, if this person was selfish enough to use their speakers in the middle of the night, who knows what more they’re capable of? At least they gave it their best shot at being passive-aggressive before they go on shouting and yelling.
