Like for example, putting on a brand new pair of fishnet hose that are not only very flattering but that you found on sale, and then, just as you get to the office, having one of the hooks from your coat snag a hole in the thigh.  ARGH!!!!!!!!!!

Or having a broken charger, going in to have it replaced (as per warranty), and completely getting the run-around.  (Why does technology hate me?)

Or how about realizing that your life is so wonderful, that you’re forced to complain about things like pantyhose and cell phones, and then feeling guilty and spoiled and ungrateful about this realization.
