Jack rarely threw away anything, nothing in the way of paperwork. It was only a few years before his passing that he found all his canceled checks, every one, saved from the very first time he was able to have a checking account to use instead of cash. They were in the attic. He must have looked through them and recalled all the purchases he made, many of them, like the checks, still either in use or in storage in the attic, "just in case." He finally disposed of the checks.
Other more important documents were stored in his safe in the house. Deeds to the house and commercial properties, birth certificates, and this one that was so important to him, his honorable discharge from the Army.
Yes, I keep it. Like father, like daughter.
