i won't hold my breath - This is what you say when you're expecting the worst and als

This is what you say when you're expecting the worst and also ready to laugh at the person who let you down.

Your mom: I won't hold my breath. Because you're still wearing pajamas at 10 AM.

Your teacher: I won't hold my breath. Because you still can't beat my high score.

Your crush: I won't hold my breath. Because you still don't know my name.
