* "I tried to soften the blow by telling her the bad news gradually."
* "The doctor softened the blow by explaining that the surgery was necessary but not life-threatening."
* "The company tried to soften the blow of layoffs by offering generous severance packages."
Essentially, "soften the blow" means to minimize the negative impact of something by presenting it in a more gentle, understanding, or supportive way.
