Hee hee. Others might disagree, but I don't think you're a bad person at all. Sometimes it's fun to poke the crazy.
For some reason that reminds me of when my husband and I had a garage sale a few years ago. We did the usual thing people do to advertise a garage sale; i.e. putting signs around the neighborhood. These signs were on stakes that we hammered into the ground, and they were professionally lettered (a friend did them for us so that they'd be eye-catching). Well, I guess they caught someone's eye, all right - when we went for a quick walk to make sure all of our signs were still up, we found that several were missing. We'd been very careful to put them on public property, so I don't know if someone thought that we'd used their lawn (we hadn't) or if they just objected to garage sales in general. There was no wind that day, so there was no way they'd blown away.
