I challenge the world to solve this riddle. I beg you to try. I failed to solve it, and I created it.
There is a house with three floors, 1, 2 and 3, and 7 stairs between each. I live on 1, and B lives on 2. 3 is empty. I want to play with Y which is a toy on the third floor, but to confirm that Y is still there, I send B to check it. B goes and comes back to 1, and says he doesn’t see it, but he needs to check in the room. So B goes to 2 to get the keys, but it isn’t there. So B first searches on 1 but doesn’t find it, and then he realizes he’d already taken it but forgotten it at 3. So he goes to 3 and checks it, and finds the keys there. He opens the door and finds Y. He goes back to 1 and informs me. Then he goes back to 2. I go to 3 but I don’t find Y there. I go back to 1 and find that my brother who lives with me has already taken it. I take it from him and go to 3, and then I realize that I forgot an important thing. I go back to 1, find the thing, and go to 3 along with Y. When I try to open the door to find X, which is also a toy and an important component of Y, I find that the door is locked. I go to 2 and collect the keys from B who had accidentally locked the door at 3 again after finding Y. By the time I reach 3 after taking the keys, it is raining and I have to go back to 1 (What a waste of time and energy). Find the number of stairs I, B and my brother took, only down (By which I mean the number of stairs took by blah, blah, blah, only downstairs, if it’s not that clear. Oh. Even this isn’t that clear.).
