This is an unusual paragraph. I am curious as to just how quickly you can find out what is so unusual about it. It looks so ordinary and plain that you would think nothing was wrong with it. In fact, nothing is wrong with it !!! It is highly unusual though. Study it and think about it, but still you may not find anything odd. But if you work at it a bit you might find out. Try to do so without any coaching.
Still got confused?
The letter "e", which is the most common letter used in the English language, does not appear even once in this paragraph.
