Just had a surreal moment at work. We're really busy doing a shedload of preparation for next year's reporting, and we had an email thread spiral out of control, being copied to half a dozen people. I mention to my team leader about how much it's doing my head in, trying to keep track of all these emails flying around every 15 minutes, so she sends out an email saying "Stop. Stop it now. Use the phone and don't clog up everyone's goddamn inbox." (Except not quite using those words, natch).
Five minutes later, a reply-to-all comes back saying "yeah, we really should be using the phone or instant messenger for this..."
