I make drinks at bars. What? Some jobs are easy to explain. It's not my fault that people like to talk about the things I do, so that talking about my job is easy using only these ten hundred words. My job isn't that hard to understand for most people; the simple words that are most used are perfect for talking about it.
In fact, writing this way doesn't even sound all that different than the way that I usually write. Even though I use less-used words when it helps to do so, I usually stick to these more simple words for almost all of my writing. So, using the "Up-Goer Five" thing just isn't very hard for me.
I've spent a lot of time learning how to get ideas across simply. I took classes in it. So this is pretty much how I talk, anyway.
