I know this maybe the hardest thing to do when storing seeds but I think the ideal and the safest way to store them is to memorize them, though it may sound very challenging, it can be done if we only have the will to do it especially if we only have a small number of wallets with significant amount of funds with it. Imho. 
I memorize it. A 12-word seed is a lot easier to memorize than most people thought.
how accidentally rave it to your friend when you drunk?
That’s why I prefer to write my seed on the pages of my favorite books in my library.

If someone knows you posted it here, maybe he will go to your library and searching this book. I don't know why are you proofing your secret in the public area?
you must move it now.
