A critic is a man who knows the way but can’t drive the car

Why do certain people feel the need to announce to me that there is one fax cover sheet left in the box when I can clearly see that for myself?   Why do certain people point out that there is a package next to my desk when I'm the only one here who would have signed for it upon delivery?  Why do certain people point out there is a spill on the counter to me instead of wiping it up for themself?  Why do certain people just stand and stare instead of offering some form of assistance when an entire coffee pot explodes all over the entire breakroom and the front of my pants?  Why do certain people ask me a mail related question everytime they put something in the outgoing mail box as if to make sure I acknowledge it and will in fact mail it out for them?  Why do certain people automatically think someone stole their laptop power cord because they can't find it?   Why do certain people think sitting in the office on their computer all day makes them appear to be hard at work?
