Riddle: You and your friend were playing hide and seek. You were the seeker, and your friend was the hider. As soon as you finish counting, you go search for your friend. You go everywhere possible, including buildings. Your friend is nowhere to be found. You look at every building, every corner, but he's nowhere. Later, after looking at every place possible exactly 3 times, your time ends and your friend comes up to you. Your friend reveals where he was hiding. What did your friend say? Rules: 1. Your friend is nowhere to be found, so no tricks with finding him mid-game. 2. If you think you've got the correct answer, please leave it in the comments along with a reason why your answer is correct. 3. Every space was open, and was explored by you exactly 3 times. You cannot explore now.
