Are you peeking or have you already given up
Give it another try....
Look at each word carefully. You'll kick yourself when you discover the answer. This is so cool.....

No, it is not that they all have at least 2 double letters.
Let me know if you figured it out. 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. Did you figure it out? No? Then send this to more people and stump them as well.
Then, you'll feel better too.
