There's daggers in men's smiles

The quote "There's daggers in men's smiles" is from William Shakespeare's play, Macbeth. This line is spoken by Donalbain in Act 2, Scene 3, as he reflects on the treacherous nature of the world around him. The play itself is a dark and tragic tale of ambition, betrayal, and the consequences of unchecked power.
