Here's how it works:
* Literal meaning: A straw is a thin, flexible piece of material used for drinking or other purposes.
* Figurative meaning: "The last straw" represents the final, unbearable event that causes someone to finally lose their patience or give up. It's like the straw that breaks the camel's back.
Example: "After weeks of dealing with her rude coworker, the constant interruptions were the last straw. She finally snapped and went to HR."
In this example, the constant interruptions are like the "last straw" that pushes the person to their breaking point.
