Sometimes I think my brain is like the grocery cart you attempt to maneuver around the store - the one with a noisy, wobbly wheel that frequently veers the nearly uncontrollable cart into the stocked shelves. I tend to notice and react to seemingly unimportant things that are usually ignored by others. A good example is my compulsion to count the skip line markings on the center of the highway when traveling as I did when attending my class reunion.
