In a standard conflict, you can walk away. In a family drama, the characters are trapped. They share holidays, inheritances, and childhood traumas. They are bound by obligation even when love has evaporated. This "inescapability" is the secret ingredient of great storytelling.

Consider a storyline where a mother is overbearing not out of malice, but out of anxiety and love that she cannot properly express. The daughter’s resentment is real, but so is the mother’s sacrifice. The drama isn't about a villain; it's about the mismatch of languages. How does the daughter say "I need space" without destroying the mother who gave up her career?

Similarly, consider the sibling who stays home to care for an aging parent. They grow bitter as their siblings travel and succeed. When the traveling siblings return for Christmas, a fight erupts. The caretaker screams, "You have no idea what I've sacrificed." The traveler screams, "No one asked you to do that."
