Staying quiet is sometimes wiser than speaking. Expressions like hold your tongue, keep mum, or zip your lip remind us that silence can be powerful. When someone says mum’s the word or keep it under wraps, it shows trust and secrecy. Being still as a mouse or silent as the grave can create calmness and peace. Sometimes we bite our tongue to avoid saying something we might regret. Whether we stay schtum, seal our lips, or keep things under our hat, knowing when to speak and when to stay silent is an art that shows thoughtfulness and control.
