Over-decorated

One of the secretaries walked into my "office" today (it's really a cubicle that's been constructed in half the room that serves as the mailroom) and said "Look at all this!"  I guess I have too many decorations in my office space (though I don't think so - some photos and a couple of maps, and now my poster of the window).  It made me so mad - I'm stuck in this shitty shared space with no window and no privacy (both of which she has!), and she feels free to criticize my decor?  Sheesh.  Way to rub my nose in it.  Why?????  I just said "it's so dreary."  I was proud that I didn't say "fuck off."  Mean Girls are everywhere.
