irritations of today

my co-worker and i (for all intents and purposes) share one office. there is a door between us, but having it closed would end up recquiring a far lengthier explanation then i ever want to deal with. however when i'm in a bad mood, which i seem to sadly be in today, i want for him to just be quiet and/or stay away. instead, i get to hear him be a complete dick to someone because the system that answers and routes his call to a particular mobile phone company takes too long. it's not their fault he doesn't know how to send photos from the phone to someone's email. (it is work related.) if it's not exactly like jm wants it, it must be all wrong. today, 'pal' you're a jackass.
