It would be more effective to get someone else to look over the text first, but there’s not always someone else around. Why is that? I think it’s because I know what I meant to type, and my brain just assumed that it communicated what I wanted to. Have you had days like that? Too often I notice a typo just after hitting Send on an email or Publish on a blog post. Wanting to make up for it, she typed a quick note of regret: “I apologize for the typing errow.” It happened way back in the days when typewriters were still commonly used, and perhaps it was the client who pointed out the spelling mistake.
The young typist must have been embarrassed.
