If you're not, you'll end up carrying a biting, thrashing, wet toddler to the car and forcing her, crotch first, into her carseat as guests look on in horror and pity and, all the while, the frantic child shouts the inexplicably mean, utterly unrelated taunt of "YOU'RE NOT BEAUTIFUL." And at this point, all you'll be able to do is hold your head high and think, "Da fuck I'm not," while strapping your remaining children into their seats and marveling at just how slowly time marches on when it's humid and your life is a shambles.
Or...you know, so I've heard. Yeah, from a... friend or whatever.
