Why do you have to make so much money?

Like any typical night, Scarlett called for us tonight well after we've put her to bed. Her question tonight was, "when is the next home day?" She calls days off from preschool "home days" and she looks forward to those. Well, my husband told her, "3 more days until the next home day." That was not a satisfactory answer. She replied, "why so long before the next home day?" My husband had to explain to her again that we need to work during her school days. She then rebutted, "why do you have to work so much and make so much money?" So my husband explained to her that we need to make money to pay for the house, to pay for her lovies, etc. Ah, kids. So blissfully ignorant and carefree.
