As much as I was thoroughly amused at Paige’s comeuppance, and while I agree that Ms. O’Dell has every right to tell Paige to knock it off with the bad reality shows next time she babysits, I don’t think what Paige did was all that terrible. All she really did was watch some inappropriate TV in front of a two-year-old, who has the attention span of a fruit fly (like every toddler). Part of the reason why the kid even picked up the word was because Paige had her right there, keeping an eye on her. The effect will surely be temporary and the kid was hardly traumatized.
That said, Paige is a big enough air-head that she probably needed being paid a penny to drive the lesson home.
