Trending ... stupid

People are exhibiting signs of a disorder that is becoming more and more common and, to me, quite alarming.  I'll have to figure out a name for it, but the afflicted seem to be incapable of walking at all, anywhere, without a paper cup in their hands.  Presumably the cup is filled with coffee, because it is almost invariably paper or styrofoam, sometimes with a recognizable brown paper band around it.  The practice defies logic, because they either try to sip the hot liquid while in motion, or they carry it prominently in front of them like it is the Olympic torch or a gift for the Christ child.  Worse still, they will almost always put it into the microwave the minute they reach their destination with the quickly cooling beverage.  And of course, in the end, much of the coffee will be dumped and the paper cup tossed into the trash.  It is multilayered stupidity at its worst.  Shouldn't coffee or tea be enjoyed at a quiet moment, while seated, and from a freshly brewed batch?  When did it become something you carry simply because everyone else seems to, or worse, something you drive to a building to get?  Would you drive through for a bowl of cereal or a toothbrush?
