''My dear and truly amazing John, John Mayer, I just want to thank you for accepting to come and participate in RiR (Rock in Rio), it was a great new for me, a huge fan of your work! I have to say that all of your songs mean a lot to me, they're so different but they always make us feel the same. If I wanted I would stay here and enumerate all the good reasons why you're such a great artist and why I couldn't live without listening any of your songs. For now, I just want to say that I'll be there in May, and I hope not to be disappointed with the amazing man you seem to be.''
And this would be an good example of a letter that John Mayer should received from one of his portuguese fans :)
