If you place your head in a lion's mouth, then you cannot complain one day if he happens to bite it off.

The remark is a vivid proverb-like warning about foreseeable consequences. By choosing an obviously dangerous course—symbolized by putting one’s head in a lion’s mouth—you implicitly accept the risk of harm. The “cannot complain” clause stresses personal responsibility: outrage is misplaced when the outcome was predictable and the hazard voluntarily embraced. More broadly, it cautions against reckless trust, courting trouble, or entering situations where power is asymmetrical (the lion holds all the leverage). The image also implies that hoping for mercy is not a plan; prudence means avoiding conditions where a single adverse turn can be catastrophic.
