What is get up and bar the door summary?

"Get Up and Bar the Door" is a well-known traditional Scottish ballad. It tells the story of a couple who live in a remote Scottish cottage and get into a quarrel one night. They both refuse to back down and agree to a compromise that whoever speaks first after midnight will have to get up and bar the door. However, when two robbers break into the cottage and threaten the couple, both the man and woman remain silent, hoping that the other will give in and bar the door. In the end, the robbers become so frustrated with the couple's stubbornness that they leave without taking anything. The ballad is a humorous illustration of the Scottish love of arguing and the importance of not giving in to threats or intimidation.
