Some people know just enough to be really fucking annoying. And some people are annoying without knowing anything, of course... but when I've taught you everything you know about a subject, it would be really nice if you listen to what I say instead of yammering in my ear at a mile a minute about how we just gotta do this we just need to do that why won't it work you need to make it do that why did they change the program (that was over a year ago, this was just fine a couple of weeks ago dammit) yah yah yayayayayaaaah... patrons can be really damn annoying. I had to tell her to shut up so I could think. Not that it helped any, because she managed to FUBAR herself rather thoroughly.
