The short answer here is, "Sometimes." We've all given up some stuff to live together for this season. Some personal preferences suffer - little stuff, like me letting someone else use my cutlery and cookware (gasp!). If I haven't told you already, I really enjoy cooking and I enjoy having nice tools for cooking. But my stuff is in the kitchen, so we all use it to cook whatever we want. I see this in a positive light - that it helps me to hold loosely to those things that could otherwise become major hang-ups.
Unless the Lord has other plans, this sharing a house thing is just for a season. We're just trying to learn what we can while we're here.
