speech and intelligence

why is it that the more people talk, the less intelligent they seem? or perhaps i have the cause and effect reversed here: why are less intelligent people prone to hours of meaningless rambling? it is my misfortune that i have to work with people who like to talk. blah blah yada yada. and it's all useless, usually consisting of a summary of previous achievements and glories. i mean, i really don't give a fuck if you were julius ceasar one day - i find nothing interesting or impressive about you. in fact, i'm here against my wishes. and the cherry on top? "why are you so quiet? everything ok?" no it's not, i'm suffering. if you'd just shut your yap and turn up the music and let me sulk in peace. if you're the talkative type it's ok, just stay away from me.
