Had him to the range yet? Congrats, Grandpa! Hehe one time I did that to a guy; his daughter wrote a column for a magazine, and in one column said she'd be away for a couple of months giving birth. They'd been out of touch for years (bad divorce) so he had no idea. I saw him in the hall and greeted him as Grandpa. Took him a moment to process, then he said "what else do you know about my family?" He got in touch with her after that, so it was good.
