Not Cool

So this stupid girl that works in the computer lab as a general grunt makes me so mad. I really don't like her at all. Today, she said some really rude shit. To one co-worker, she said "go ahead and touch the xmas lights (that she believed contain lead) since you're never gonna have a baby"...she may as well have said you're an ugly old hag- and this woman is beautiful and intelligent. To me- generally inappropriate comments about my weight such as "fucking eat something" (I had just come back from lunch with her boss so..) - I don;t tell her to stop eating so many things- that would be rude- why isn't it rude the other way around? I mean if I said- you're a fat moron- Im pretty sure there would be a problem...is this ummm reverse fatism?
