When we do something stupid, it is sometimes that we have forgotten something: a friends birthday, to shut off the oven or to take the parking break off while driving.
But there is another genre of stupid things that I am more interested in. The kinds of things that are stupid because you were thinking too narrowly. There you were hitting the key of A in all different ways, standing on your head, hitting it with your pinky toe, throwing rocks at it, only to realize that you should have been hitting the key of B in order to evoke the sound that you wanted.
Sometimes someone comes in while you are doing your key-of-A shenanigans, and points out that you might try hitting B instead. You relax your contorted body and sigh, and you feel the stupidness all over. Other times its you who realizes your mistake, after some time away or after you have banged your head a few times on the key of A and it just hurts to much to continue in this manner.
It is both a great and sorrowful moment when you realize your ridiculous narrow thinking. A door in your mind opens, but sometimes it is difficult to believe that it was ever closed.
