'It's now Wednesday. She still has my car': Golden Child says she'll return her sister's car after 1 hour, ends up bogarting it for 4 days without permission before coercing the family to side with her

My parents are pretty old school, so I was taught that when you borrow someone's car, it needs to be returned before they miss it with a full gas tank, a fresh car wash, and a new air freshener. It may sound like overkill, but that's the kind of borrowing mentality that encourages people to continue loaning you things. It must return better than how you got it; it's as simple as that. 

However, the rules for siblings are a bit different. While growing up, siblings will squabble over the bigger ice cream scoop or the best color of sleeping bags at the sleepover, but usually the best, biggest, or most glamorous choices will go straight to the Golden Child. After a lifetime of getting first pick of whatever they want, Golden Children expect the world from those around them, and give back nothing in return. 

So when a woman loaned her sister her car, she should have expected her GC behavior to translate to the rules of borrowing, but after "1 hour" turned into a 3-day carjacking, drastic measures had to be taken.
