Everyone knows that feeling - you're having a wonderful day and one little thing, sound, smell, memory or a person ruins your entire day and you burst out crying. Sometimes even without a reason. I think it's not exactly 'without' - for me, we don't know why we're crying when we're having waaay to many problems on our mind and can't guess which exactly made us go 'oh hell no, now that's something i won't handle!!! -.-' and made our tears fall down. My opinion, we shouldn't show our weakness... too often. But sometimes you just can't hold back anymore, so you sit / lay and cry from helplessness... But just think-don't you feel much better then?xD Nothing happens w/o a reason and after 'a good solid crying' we have the clearier view on the world and we feel muuuch stronger ;) Or at least, like 'I don't care'.
