On A Serious Note
This poor kid is in desperate need of therapy. I don’t know why your dad left and never came back. Maybe he was abducted by aliens. I know that’s what my cousin thought when his dad left but as it turns out he was just living with my grandma and working at Dairy Queen. We were all disappointed.

People do a lot of things that make no sense. Maybe you check out your local Dairy Queen. You might get lucky. Or maybe check your grandparent’s house. If you still can’t find him after that, assume it was aliens and just learn to accept it. It’s his loss anyway. You seem like a pretty awesome kid.
