Idiom: Don’t Make A Song And Dance
Example: “Don’t make a song and dance about it; I’m only a few minutes late!”
To make a song and dance about something is to over-react, and treat an incident as more serious than it really is.
Sometimes people say, “Don’t make a production out of it!”
A song and dance is a big production. If you find a really interesting story, why not make a musical of it? The speaker above is saying that him being a little late is not an interesting story – not important.
