Please accept my heartfelt condolences on the loss of your dad.  I guess that means that you're an "orphan" now.  It doesn't matter how old you are, when you've lost your parents, it's a catastrophic event.  I'm glad that you've had the many years with your dad and that you've got those lasting memories to comfort you in your loss. 

Keep in mind that this has only been the beginning. 

What awaits us on the other side is eternal.  :-)
