I swear I'm going to set this place on fire.......

I'm having a Milton moment.
I was using a chart in the back room of the nurse's station. There's a big round table, sits 8 people easily, where we can all work.  I had a chart open, a pad and pen out, and my water next to the chart- all signs that any intelligent person can deduce that that is someone's work space.  I got paged and went to a phone to answer said page.  When I came back, my stuff was moved, the chart was closed, and my pad and pen were thrown across the table. Oh, did i mention that the entire table was EMPTY except for my stuff? Fucking genius couldn' sit on the other 8 seats or on the other side of the table. MY space was the one she HAD to sit at?! Are you fucking kidding me?!  So I very noisily gathered my things, disrupted her work. Why? because I don't give a shit. If you're going to be that dense, then you will suffer the consequences.  She looks up and says "Oh, were you sitting here?"  Really. How fucking clueless can one person be?
I swear I'm going to burn this place tot he ground. But I'll make sure to take my stapler.
