It's awfully easy to misconstrue things on the Internet when you can't hear the tone of a person's voice. I once got very pissed off because someone used the phrase "I can't believe..." in response to something I said. Now, "I can't believe that X happened" can be construed two ways. It can figuratively mean "I'm surprised that X happened" or it can literally mean "You're a liar if you say that X happened." In the context of the discussion, I took it literally, but on reflection, much later, it occurred to me that it might have been meant figuratively.
