It is generally considered to be bad etiquette to let a dog poop in the middle of the street and so having neighbors who always do that is not amazing at all.
Consider the statement "It's so gross that my downstairs neighbors always lets their dog poop in the middle of the street.". Based on this "It's truly amazing how my downstairs neighbors always let their dog poop in the middle of the street" a true statement? Yes, no, or I don't know?
