When we say “you crossed the line”, it means someone has gone beyond the limits of acceptable behavior or actions. It’s similar to saying “you’ve gone too far” or “you’ve overstepped your boundaries”.
Here are two examples in sentences:
Example 1:
When Mark made fun of Lisa’s family, she told him, “you crossed the line”. She was upset that he had disrespected her loved ones.
Example 2:
The teacher told the disruptive student, “you crossed the line” when he started throwing paper airplanes in the classroom.
Here are examples in a conversation:
Example 3:
John: I just thought it would be funny to post that photo of you online.
Sarah: John, “you crossed the line”. You should have asked me first.
Example 4:
Dave: I only took your car for a spin. What’s the big deal?
Sandy: Dave, “you crossed the line”. You didn’t have permission to use my car.
So, when you say “you crossed the line”, you’re indicating that someone has behaved in a way that is not acceptable. This phrase is typically used in situations where personal boundaries or societal rules have been broken.
