The argument on day twelve wasn't actually about the empty milk carton left in the fridge; it was about establishing boundaries in a shared space that suddenly felt much smaller than it had a week prior. Week 3: Deep Waters and Old Wounds

We decided to host a small goodbye dinner for her last weekend. She cooked (successfully, this time—she’d been practicing). I decorated. We invited our parents, my boyfriend, and her best friend.

This is a full account of the lessons learned, the laughter shared, and the inevitable frictions of a "30 days life with my sister" experiment. The Premise: Why 30 Days?
