Respectfully, if I am way off base, please forgive me, but you outta rethink this. Maybe he feels that you attained something in your life that he never could, whatever that hobby would have been, and your invitation just reminds him of what he feels is failure. Don't know what kind of circumstances you grew up in or how he feels about himself. If you have never seen "Fields of Dreams" it is about the anger a man has towards the "wasted" life of his father. But what it brings out is that we often do not know our fathers when they have life in their eyes and fire in the bellies before the world tears their balls off and leaves them a broken shell, and until we experience the same, we really are unable to relate.

Try to accept him for who he is. You are angry and when he does go, what you might find is that you may not be grieving him as much as the loss of the hope of the opportunity to have related successfully to him. that grief is much heavier.

Regardless of how he chooses to act, it is not a statement about you and more a statement about himselff.

It funny. I hate rap. But my son recently sent me a link to a song called "Yesterday" by Atmosphere. Very touching. If you do, listen through the end.

I hope I am not coming off too strong, but I probably am. It is something I feel so strongly about that I do get intense about it.

I hope things improve for you with your Pop.
