I talked to my principal, and we agreed that I could use my room to pump...I put paper over the little window, the door is always locked, I formed principals, tech lady, and custodian that during 3rd period and lunch I'm pumping.  I even put a little note above the lock on my door so they would see it if they had to unlock the door to let themselves in...

3rd period I hear someone messing with the door, I lean down and the tech lady comes storming in, leaving the door wide open behind her.  Weirded me out, so I asked her to shut the door. She kept walking towards me and said, "Oh I will, I'm just taking inventory on ink to see how many I have to order." 

I said "I need ink, the orange light is on..."  She continues to walk towards my little corner of the room, around my desk, and peaks under my legs where the printer is.  Then left.

 Uhh...is she really that dumb that she didn't notice it was my personal time?  Could she not hear the pump (whish-whoosh, whish-whoosh)?  Is she that ignorant that she couldn't even offer an apology for being so freaking rude to not trust what I said about the printer and honor my personal space/time?!

Everyone at my school has stories on why they don't like her & I felt a little bad for her...but now I have a story, too... ARGH!
