Each Friday morning I post a riddle to get you to think outside the box and exercise your brain. If you are stumped, share it with a friend or colleague and see if you can figure out the answer together. Leave your guess in the comment section.
This week’s riddle: It has keys, but no locks. It has space, but no room. You can enter, but can’t go inside. What is it?
I’ll approve responses later in the day to allow people to respond without seeing any spoilers.
