a desperate pergunta

I don't see why not. Of course, you must be very very patient. The results may be immediate, or not, depending on whether or not he is in the area that night. Make sure you believe and focus on him coming. When you write to him, put all you love, happiness, joy, and childhood memories in your writing, and it will call out to him ;) Hope this helped! Remember, if you have faith, and trust, he'll bring the pixie dust :)
