Ok, speaking as a librarian.

DON'T MESS WITH MY STACKS.

If you take a book out and put it back in, fucking PUT IT BACK IN!

Don't all shove it in all fucked up and like push six other books so far back behind it no one will ever see them again.

Don't do it. Be a man (and/or woman, and/or transgender indivudual, or whathaveyou) and put it in right, bitch!

Oh, and shut the fuck up, while you're at it.

Shhhhhh!!!!
