An Obnoxious Co-Worker

Every Wednesday I have to work with someone who just doesn't seem to understand why we're all there in the first place. She is consistently late, goes shopping during work hours, keeps going to her car to bring in her junk, and is very loud, rude, swears a lot, consistently invades my personal space where I'm working even though I've told her more than once not to, and generally carries on like a... well, I was going to say "turd", but that would be rude, so I'll refrain from doing that.
Tomorrow is Wednesday, so we'll see what happens. If she gets on my nerves again, I'll just let the boss know what she gets up to, and hopefully she'll be gone!
And I'm posting this just because I needed to get this out of my system. Complaining about stuff helps my mood.
