What this quote means

This metaphor comparing love to a cough suggests that love is impossible to conceal. Just as a cough manifests physically, love betrays itself through visible signs: glances, smiles, gestures. You can't hide it for long because it emanates from us naturally. It reminds us that love is a powerful and transparent emotion.

How to apply it daily

Notice the signs of affection you show spontaneously toward someone, and let them express themselves without suppression.
