A: Two weeks after Mary was dumped by her ex-boyfriend, a burglar broke into her rented apartment and stole her laptop.

    B: That was the last straw for her. She finally packed up and moved north to start a new life.

    Note: This idiom means the “final additional small burden that makes the entirety of one’s difficulties unbearable.” The full version of this metaphorical phrase is “the last straw which breaks the camel’s back.” It has an Old Testament sound about it. Searches there produce many references to straw and camels amongst the smiting and begetting, but no “last straw.” Some suggest that the phrase is a variant on an old proverb “it is the last feather that breaks the horse’s back.”
