A vs. The administrative assistant, Round 2

Today I'm forced to admit, quite shamefully, that I crumbled. The administrative assistant came in to where I was working and complained about my (intentionally) not filling in the pay period on the time sheet again. After I series of monosyllabic replies, she dropped the paper on the desk and said that she wouldn't file them if I didn't fill out the pay period and that I wouldn't get paid. I stewed in my anger for a while, not really believing that she would actually keep me from getting paid, and contemplating just not getting paid (with the financial aid I'm getting, I actually don't need the money. I'm just hoping I can save up enough to not need to take out a loan next year). I eventually caved, though, and went to explain my case (I've worked there for almost 4 years now and never filled in the pay period, but no one made an issue of it until this summer). I tried to get across how annoying her condescending attitude it, not just about this but also in other incidents of the past, but it really was beyond her and I totally lost the battle. She didn't even express regret for the toilet flushing episode that I found rather humiliating (honestly, it's a toilet. Sometimes there will be some brown streaks at the bottom of the bowl. I have literally shoveled shit, so that's nothing). I was angry for a bit after that, but, really, she's a very pitiable figure. Alone, no husband or kids, can't even have animals because she can't deal with cleaning up after them. All she has is work and being anal retentive. What a sucky life.
