This site is really cool, lol. If you've got someone that you want to tell them something and you can't bring yourself to do it, just get on this site and you'll find a hotline number. All you have to do is see that they get a message to call that number.
They've got a lot of different categories from everything like "You've got bad breath", "I love you", and break up messages.
Take a little tour and call some of the numbers yourself. They're pretty amusing.
