I don't understand why you pretend to be a retard when you're not.
Because it's so god damn FUN.
Because people being serious all the time are CRINGE.
Because other people are taking a LIKING to it, if they have a sense of humour, and if they don't they just avoid, so the absolute stuck-up RETARDS, filter themselves out.
Because NOTHING you do will ever matter anyway, so why not do what you can to escape that.
Hey what the fuck, I'm not acting retarded.
Pretty sure User's just projecting his insecurities onto you, there's been a fair amount of Nihilistic themes in his justifications for acting "dumber" than his believed idea over himself.
