Phew
This night I really felt like writing this comment.
I got some hints from a certan somebody who´s really something and realized the real meaning of this picture.
Well, the ballon reacts like a magnet - always in one direction
It does what it has to do.
Maybe I´m a bit maudlin but the baloon flew to sky and has no intention to fall down together with the boy´s letter so I think the boy is right.
It truly reached heaven.
