The sisters have officially descended on Nantucket for the summer, recording from bed on day four of commune life: 11 adults, six kids, and zero personal space. Clare has prepared Andrew a full orientation guide (no sleeping in, house chores mandatory), Erin woke up at 4am with her OCD reaching new heights, and Megan's camp counselor energy can't be contained. Also on the agenda: the crusty versus greasy personality debate, puka versus chain, a live CoStar reading under the Strawberry Moon, and a tick paranoia spiral that ends with Erin offering to check Clare's butt. That's what sisters are for.
