the hole on the wall

I had my best tools. The best tools, that the 21st century could offer. Laser liner, electric screw driver, electric drill, well designed shelf and screws, EVERYTHING. And about 2 hours later when I finished the installation of our new furniture on the "kitchen/dining" wall, my lovely wife just simply said: "It's not straight!" - for the first 15-20 minutes I tried to prove her wrong with all my tools but couldn't trick her (and not even my!) eyes. It just wasn't straight. Obviously, we had to fix it somehow and a good ol' hammer and a nail did the trick, however we still have an inch wide and deep hole on the wall. Tell you the least, she was not happy.

The following day I consulted with at least 3 married couples and they all (each and every one of them!) had their own story about the hole on the wall. Some of them covered it with a picture or a curtain or just left it there for future reference :)
