a desperate 问题

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