Assess         Give it another try....   Look at each word carefully. You'll kick yourself when you discover the answer. This is so cool.....   REMEMBER I ONLY SENT THIS TO MY SMART FRIENDS NOW DON'T LET ME DOWN   No, it is not that they all have at least 2 double letters....   Answer is below!                                   Answer:   In all of the words listed, if you take the first letter, place it at the end of the word, and then spell the word backwards, it will be the same word.
