Joshua has been taught all sorts of bad words by his uncle. You'd left him to stay at your brother's house for a week so that you and your spouse could have some time to yourselves. But, to both of your surprise, the little brat's been spewing out all sorts of profanities the moment you put him inside of your car to take him back home. Your spouse is horrified, refusing to talk. Meanwhile, Joshua's having the time of his life, giggling away as he runs around and cusses out loud.
"Your cooking looks like shit," Joshua chimes as you set his plate of lunch in front of him. Clearly, he's been learning a whole lot of stuff that he shouldn't have been exposed to at the age of five. You wonder how you're going to stop this new habit he's developed.
