All of those symbols and stuff trigger my latent dyslexia ADD. It is similar to what happens to me when I open the instructions contained in a box that says SOME ASSEMBLY REQUIRED. My eyes roll to the back of my head - if lucky I won't start frothing at the mouth. I'm being facetious, sort of, about the effect ASSEMBLY DIRECTIONS have on me but they might as well be written in egyptian hyroglyphics for me. Back in the old days if I looked helpless long enough and the box was left in the middle of the floor long enough someone would take pity on me and put it together, usually in 10 minutes or less without even glancing at the directions. A humbling experience.
