There is no excuse for littering.
Hello Kitty even knows that, and is watching you to make sure you follow through. Just check out this piece of graffiti, tweeted by @LeNajib, and you'll know exactly what I'm talking about. With the Arabic text, "Please don't litter in the street," the graffiti is drawn on a wall that's strategically occupied by Hello Kitty, giving the message a more lighthearted tone.
Because who wouldn't listen to that adorable face?
