You Have Family Over
We're glad that you get a home cooked meal and a long overdue game of Apples to Apples with your flesh and blood, but don't force your roommate to feign three hours of small talk. Oh, and your grandma's catheter bag is in serious need of draining. Thanks, we just lost our appetite.
While this might seem like a minor gripe, being cordial for hours on end is absolutely exhausting, especially in your own apartment. Give your roommate a break from "family time" and take your next shindig to a Six Flags.
