Perhaps it's code for something secret, like where to find some hidden treasure... Hmmm, that would be nice, wouldn't it?

I'm guessing it's either 1.) to remind you that you're not the oldest. or 2.) Your dad has no idea what he put in there. It's the kind of weird cryptic messages I would get from my grandfather in his later years, so I don't mean to be harsh... But I figure there would be other things that would make something like that apparent.

Chances are, it's #1.
