What does the idiom “What’s Good for the Goose Is Good for the Gander” mean?
Women and men should be treated equally in the matter under discussion.
“I was worried about how Cynthia would react when her boyfriend took another woman to the movies. But I just saw her with another guy. What’s good for the goose is good for the gander.”
A variant is “what’s sauce for the goose is sauce for the gander.”
