The final lesson every kid learns is to lie to their parents. What else are you going to do later in life? It’s the only way you’ll be able to dump them into a nursing home and take their house before they realize what’s going on, later. But if you get caught, you have to have an excuse that’s already half true. Wreck the family car? It was stolen (technically by you). Get someone pregnant? You had protection (in your glove compartment). Fail out of medical school, you’re still a doctor! (if you call chiropracticing “medicine”).
