 When you fold them over, they make a noise. They're not soft anymore, and it feels almost as if there's some plastic in there or something. They make them differently, and I would never now attempt to tie a piece of brown paper back on my finger and cut it because I wouldn't trust it. I don't know what's in there. Do you know anything about that? Is there a difference in the quality of paper bags in maybe 30 years or so?
