Staying in is an art form. In a time with plenty of social pressure to attend birthday parties, pub hangouts, and Instagram-ready restaurants, sometimes it's more fun to spend a special night in the space you're already paying for.

Make food, or have someone else do it for you. No matter how you work it out, at the end of the night there won't be anyone barking for last call unless it's you urging the dog to get off your lap. Here are a few categories to check off that will ensure when you stay in, you stay in like a boss.
