answer on a postcard
1. A brief, concise answer, reply, or opinion, especially one meant as a quick response to a general question. I'd like to get people's opinions on where to go for a summer vacation. Answers on a postcard, please!
2. An answer that is considered obvious or self-evident. We'd like to get into more complex reasons for inequality, so please avoid just giving answers on a postcard.
