My dad never denied he snored, he knew it was like a freight train running through the house. He didn't realize it was his snoring that woke him up, though.
For that matter, he knew the dog was at fault either, lol.
Snoring is mainly due to being overweight and it doesn't have to be by much.
I'm going to have to disagree with that. My father was not overweight, and my ex wasn't either. Not by a long shot. I would guess that my father had a deviated septum (honker to rival Jimmy Durante), and my ex was a mouth breather.
