It's rude to dictate what your children's surnames will be.
John and Andrea are expecting their first child, which they know will be a boy from the ultrasound.
John wants to name his new son after his grandfather, Bob.
John explains that he was very close to his grandfather and appeals to Andrea to allow him name their first son Bob.
John insists that the name of their first son will be Bob, and he will not entertain any other ideas.
Andrea agrees that if they can pick a name that they both like, they will use Bob as a middle name, as a compromise.
Andrea gets angry and tells John that she will not approve the name Bob, no matter what, leaving both new parents upset.
