to burst your bubble
to tell someone something that makes them feel less happy or excited · to ruin someone's good mood or positive expectation
What's the situation?
Imagine your friend is super hyped about a new plan, but you know it's not going to work out. You use this expression when you have to gently (or sometimes not-so-gently) tell someone something that will probably deflate their excitement or expectations. 😬 It's like popping a perfectly formed soap bubble of joy with a pin of reality! 💥
