Silly things that make you irrationately/unproportionately annoyed or upset

I hate being interupted during a project with one of those "OMG THIS IS SO IMPORTANT" things only to find out it is something a monkey with a broken tail could do. Or with something that the person bothering me could have done in the time it took to find me and tell me.
I am the lone GD for the entire company and can't stop what I'm doing to show you ( again ) how to add text to your email signature or a picture.
