Tell me at first glance you didn't read the first word a bit differently?

If it's true that it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoetnt tihng is taht the frist and lsat ltteer be at the rghit pclae then it would make sense that you read that word differently, but still, it could've been that you saw what you wanted to see.

Now that you mentioned it I noticed that in the second word a letter is missing.
