Yeah,I agree I actually think it would be very stupid if J.K. would get Sirius back,but he as a painting is geting him back,it's just some kind of memory on him,and Harry could talk with him sometimes and we could laugh at his jokes and everything.
Well anyway,I read today the part with his death again today and I think it's time for me to accept it and to let him go.Goodbye Sirius!
