When someone reads something that I write and doesn't understand it, this is correctable.
There are times when I question whether someone even bothered to read what I wrote, because if they did, they wouldn't have asked me to do the particular thing that they asked me to do, since I explained in great detail in what I wrote why it couldn't be done.
Well, it can be done, but you have to do this other thing first. And since I wasn't told to do the other thing, I kind of suspect that they didn't read what I wrote, that "other thing" requiring a certain level of planning before I can run off and do it.
So, is that cryptic enough? :)
