Never try to eat a raw potato, it could give you a tummy ache. Trust me I would know.
Never try to poke yourself in the eye with a pen and if you ever do, do not do it for free. I get that this advice might seem highly specific but trust me, you do not wanna end up like my cousin.
Never talk to or accept candies from a stranger and never ever ever everrr try to accept a stranger's invitation to play detective, even when the said stranger has reassured you again and again that they will kill you, your parents and even your extended family, and will also quite possibly dig out your ancestors from their graves and would even go to the lengths of pissing on your grave just for the hell of it.
Because I did. And let me tell you, it did not go well.
