one day, a crow kept on annoyingly squawking and gawking at your window, so you got out and threw a rock you found on the ground at it, it flew away but it remembered your face and since it told it's entire murder (not that kind of murder, a group of crows is actually called a "murder" instead of a flock, Google it) about you and how you treated it, both the crow and it's murder annoyed you every day by loudly flapping their wings at you and throwing stuff at you, even nosediving towards you and pecking you, not giving you peace, and since the word about you is spread through generation after generation, you will be in a squawking nightmare for years, and i mean YEARS, all because of that one annoying crow
