basic hygiene

so here's the deal. i'm sitting on a bus at Tech expecting a peaceful ride from the parking lot to campus. i get there pretty darn early so usually the bus is fairly empty, but there are an unsual amount of early birds today. suddenly someone comes and sits next to me who has obviously not bothered to brush their teeth (or probably bathe for that matter.) not only is this person's breath a foul entity akin to the Seinfeld B.O. issue, but said person insists on heavily breathing through their mouth. wtf?!?!?! this isn't France, people!!! it's the U.S.- hygiene matters!!!
