I'm either getting too efficient...

... or too bored at work. Yesterday, I was pretty much done work at 300 pm. Now, it's 200 pm and my "In" basket is empty. Well, not completely. It's just holding things that I'm waiting to hear back on. So what do I do now? There's nothing to file; I'm already prepared for next week's payroll; and I've been on the internet a few times already. I guess I'll just try to look busy?
