rude is the new black

i dont know if i am just getting old and cranky or if people are really getting ruder by the minute.  i have worked many different places thru my life and have never worked anywhere as rude as the place i am currently at.  you cannot have a conversation in a cubicle, office or hallway without someone feeling entitled to interrupt!  let me first clarify that i do not work in an industry of any importance to the human race.  we do not save lives, basically we make money and dont really give back to the world in any discernible way.  so, what could be so damn important that employees would feel they have the right to just walk right up and interrupt?  and not only that but the people you are talking to dont even get upset and let the person know they are being rude but then they also do it all the time so there you go.  i love the extra arrogant ones that just barge in put their dirty shoes on someone else's desk and start talking over the people already there, wow, who told them they were so damn special and where are they so i can smack them for raising such an arrogant a hole!  my favorite is when one of these people start complaining about how rude people are!  oh, that is just priceless!  i have manners, i dont just interrupt a conversation, i will walk away and WAIT MY TURN, i was taught that in kindergarten!  but why do i bother, i give them their time but they cant give me mine.
