Enough. The answer is the Grand Canyon. We were hiking but became seperated. I shouted out "Where are you?" to you as we couldn't see each other. The repeated question was the echo of my voice off the sides of the canyon. Nice try with the echo places, though!
I'm in such pain but there is nothing physically wrong with me, no scratches, bruises or cuts. What have I hurt?
Lateral thinking. Something your country (and mine and probably most countries in the world) severely lack.
I just thought of another one, so we'll have two running at once: I am doing some DIY, I am hanging a picture on a wall. It is a normal plaster wall with nothing special about. No matter how hard I hammer the nail, it won't go into the wall and even if it did then I'd have real trouble hanging the picture on it anyway. Why?
Because you're my upstairs neighbour? You're dreaming. You live in a universe where time runs backwards. You've got no string.
Nope and Nope. Sometimes the answer is the obvious answer but that fact makes it not so obvious, as you have just experienced.
