What is often returned but never borrowed?
Common Wrong Answers
“A book”
A book is something that can be borrowed and returned, which contradicts the premise of the riddle.
“A favor”
While a favor can be returned, it is also typically borrowed or requested from someone, making it an incorrect answer.
“A phone call”
A phone call can be made and returned, but it doesn't fit the idea of something that is 'never borrowed'.
