We have a Book of Questions in our house. In the book are questions we’ve raised during the day, at the dinner table, or anytime really. But we don’t attempt to answer them. We ask a question, determine if it’s worth adding it to the book, then hand-write the question in the book and leave it at that. It’s like a tiny rebellion against always having answers at your fingertips, whether through Google, Siri, or—like early Star Trek—a simple inquiry to a voice-activated device like Amazon’s new Echo.

We leave the questions in the book and come back to read them every now and then. There are some good ones worth wondering about and permanently leaving unanswered. Why? Simple curiosity. It’s worthwhile not to know something if it doesn’t really matter, which is most of the time. Less mental energy—or not if you want to ponder and guess and make up stories or create answers that make sense or are ridiculous but partially plausible, which we do. That’s the beauty of asking questions and leaving them unanswered, or answering them in any way you see fit. And here’s a smattering of a few in our book:

• What if dogs migrated?
• What does outer space smell like?
• Are there any people who still believe in the Greek gods?
• Do dogs pee right-legged or left-legged or are they ambidextrous?

Some questions are a little less ridiculous, like “why is the sky blue” or “why doesn’t fog come into your house.” Even though these questions may be real in the realm of science and industry, we don’t feel compelled to answer them definitively in the realm of our family. We only feel compelled to guess and surmise, which is good enough.

Feel free to add your own. Just don’t answer them (or the ones we post here). If you want answers, try Quora, the social media site that tries to take all the wonder out of the inane things about which you may wonder.

Update: we are now up to fifty-eight questions, some strange, many serious, none answered. Our newer ones include:

• Does a turtle’s time pass differently than other animals?
• What is the actual definition of flying? Is there a need for a certain amount of time in the air?
• Do whales fart?
• What is the opposite of brown?
