Here are a few examples of how this saying applies:
* A parent who promises to spend more time with their child but is always busy with work. The parent's actions (being busy) speak louder than their words (promising more time).
* A friend who says they will always be there for you but isn't there when you need them. The friend's absence (action) speaks louder than their promise (words).
* A politician who promises to fight for the people but votes for policies that hurt them. The politician's votes (actions) speak louder than their campaign promises (words).
Essentially, the saying highlights the importance of consistency between words and actions. When actions and words don't align, it often leads to distrust and disappointment.
