Are you tired of hearing: You never said that, I have never heard that etc., then this is the side for you.
Now you can create and save your own statements and send it right back in the face of your friends: See, at this date I told you this would happen and what happened? Exactly what I told you.
Just told someone something you know is going to happen? Go create your statement.
When time shows that you were right all along, you can activate it and send the link to your friend to remind them to listen to you more often :o)
