Sisters share everything from the day they are born. They share toys, they share friends, they share bunk beds, and they share clothes. It's tough not to get a little protective over your things if you have a sister who's hellbent on taking everything for themselves, but when it comes to adult sisterly relationships, there's a line you can't cross when it comes to your sibling's stuff.

Take, for example, the two sisters in our next story, who just so happened to be pregnant at the same time. Knowing they had a longstanding tradition of keeping the family name in the lineage, the older sister decided to name her baby after the family name. But when little sis realized that her older sibling was following tradition, she immediately latched on, saying, 'MINE' to the baby's name and steeling herself to curse the family with two cousins with identical names.
