Now stand in the corner, and think about what you've done! - Taylor Swift

Just being a human being, I’ve realized that before every big problem you create for yourself, before every huge mess you have to clean up, there was a crucial moment where you could’ve just said no.

American stories, burning before me
I'm feeling helpless, the damsels are depressed
Boys will be boys then, where are the wise men?
Darling, I'm scared.

There is a time for silence. There is a time for waiting you turn. But if you know how you feel and you so clearly know what you need to say you'll know it.
I don't think you should wait. I think you should speak now.
