Script (guión): Idioms, ‘at each other's throats’. If people are at each other's throats they are fighting and arguing ruthlessly. My wife and mother-in-law were always at each other's throats when they lived together. ‘Where are my shoes? Have you burned my shoes again?’ Lots of ridiculous arguments. Now she lives with me, they get on much better but I do worry about the family holiday that's coming up soon.
