Universal PicturesYou all know which day Im talking about. The day a group of stay-at-home mums come in with their children, theyll pick the most awkward of spots to congregate and dump their prams in the most inconvenient of places (usually blocking the fire escape - because who needs those, right?). Theyll order their skinny lattes and sit back and enjoy their morning, perfectly aware that during their chitchat their kids have run wild. They stampede around, scream and have their tantrum, leave crumbs everywhere and spill their drinks. Its utter carnage.
