the ability to laugh at yourself

They say the ability to laugh at yourself is a good thing? Well… considering that I am proud to say that I can use power-tools both left or right handed, (maybe too proud), how did I manage to mash the IKEA assembly process of my Rigga coat stand so well? Only after I had tightened the last bolt with the supplied Allen Key, did I realize the whole thing needed to be completely taken apart and re-assembled.
