First i heard

The girl once said "you know the monsters watch you when you sleep right?" While she was eating dinner with her mother and father, they looked up wide eyed at her, then eachother astonished "but" she continued swallowing a bite of mashed potatoes "if you tell them good night guys and place an open wooden box beside your bed theyll leave you alone for the night and even close the box for you, but you also have to open the box for them too and tell them good morning. Picky they are, very picky" she trailed off finishing her food and heading off to bed,
