I sometimes envy natural squeaky wheels, people who enjoy fighting. It does seem to be a basic part of life, after all.
Self-advocacy doesn't come naturally to me. If I think I'm being overlooked or taken advantage of, I need time to draw up a case and learn the arguments that will bolster it. And no matter how reasonable or even minimal my request is, it always occurs to me that I might be met with a "How dare you?" or a "Fuck you" enforced with a hammer-blow to the head. Of course if that were to actually happen I know it's time to escalate. But the wait makes me nervous.
That said, the occasion that triggered these thoughts resulted tonight in my sending a politely worded email and receiving a polite email and mostly getting what I wanted. So my not being hot-blooded isn't totally a bad thing.
