Families rarely say exactly what they mean. A passive-aggressive comment about the dinner menu can actually be a critique of a lifestyle choice.

A DNA test, an old letter, or a sudden confession reveals a hidden truth, such as an affair, a secret child, or a past crime.

"I gave you everything." "After all I’ve sacrificed." These phrases hang over complicated families like storm clouds. Emotional debt is the currency of family drama. Characters keep ledgers—real or imagined—of who owes whom. The most explosive moments occur when one character tries to "cash in" that debt, and the other refuses to pay.
