A lot of people say "Well that's a good question." but what is REALLY a good question?
Some people use the phrase "good question" to describe a question that is worth asking. For instance, a man goes to buy a computer, and is being helped by a worker at the shop. The man asks "Well, how expensive is the computer?" and the worker replies "Good question!" A good question can be considered a question that is useful, one in which the answer to is information that you need to know.
Some people use the phrase "good question" to describe a question that stumps them, and makes them confused or shocked. For instance, a person asks someone "Why is the sky blue?" and the person replies "Good question..." Because honestly, why the sky is blue is a common question that not many people know the answer too, and is generally considered a tough question, OR, a "good question".
In some cases, the phrase "Good question." is used as a way to say that you don't know the answer of something. In example, you ask your girlfriend "Hey, where's the potato chips?" and she replies "Good question." While the question "Where's the potato chips?" is generally not a hard question, nor is it a useful one, people misuse it as a way to basically say that they don't know the answer to said question, regardless of how simple or useless the question may be.
Just some food for thought.
