Open communication is always better than arguing
There’s definitely a prominent lesson elsewhere in this episode about respecting the rules of the U.S. Postal Service, but the moment when Tina suggests Bob encourage his dreaded in-laws to talk through their issues—rather than have the same silly argument over and over again—is a Belcher breakthrough. After massaging the situation further with a fake phone call so that Linda’s parents will believe Linda’s ne’er-do-well sister is actually incredibly wealthy, Bob achieves the impossible: peace on Earth, or at least in the family’s living room. (Season 10, episode 10, “Have Yourself a Maily Linda Christmas”)
