Your point being..? A riddle does usually have an answer…
In case you don’t know what a riddle is, let me explain: The definition of a riddle is basically a joke that has a question and an answer. Someone asks a question, sometimes starting with the word what, for example, “What does a fireman say,etc?”, then you are supposed to say, “What?” and then they tell you the answer which is supposed to be funny.
got it?
Alternatively, instead of saying “what?”, you can try to guess the answer, like I do in my second post above.
