Work is slow

I'm pretty efficient here at work. I eat lunch late, so I get a ton of stuff done in the morning. When I come back from lunch, I'm pretty much done, and there's an hour when nothing happens. I kill time. I'm in that hour. In a few minutes, I'll get three phone calls at once. Two faxes will come in. One will be spam, the other an Rx pad order. I'll get eight emails. They'll all need immediate attention and I'll lose track of one until tomorrow morning.
