Flattery is like cologne water, to be smelt, not swallowed.

Summary

This quote means that flattery should be appreciated and acknowledged, but not taken too seriously or believed completely. Similar to how cologne water is used for its pleasant scent, flattery is meant to be enjoyed momentarily. It warns against naively accepting flattery at face value, as it can be manipulative or insincere. Instead, one should remain cautious and discerning, understanding that flattery is often used as a social tool rather than a genuine expression of admiration.
