I found three bags of shredded paper on my front doorstep this morning. That's good, because I need them to clean out the chicken shed and replace the bedding. But I don't know who left them.
Sometimes the secretary at the kids' school gives me bags of shredded paper. But I don't think I've ever asked anyone else for shredded paper, or told anyone I use it. I suspect my sister Steph has been talking to someone over the weekend.
