This page is about the conversational phrase why not?
You can say this to show you agree with a suggestion or accept an offer.
- "Do you want to go for a walk?"
"Sure, why not? It's a beautiful day."
- "Would you like to share a taxi?"
"Yeah, why not? No point wasting money."
Used here as a rhetorical question, but "Why not?" can also be used to ask a question, as in, "I'm not going to work today." "Why not?"
Brad said, "Let's go dancing," and Angie said, "Why not?"
