"The screen does not come all the way down to the bottom and we found it was too dangerous for our hilly, windy patio."
I imagine this continuing: "We understand, however, that there are those who value their lives, their property, and the well-being of their neighbors less than we do. For you, this forest-fire-waiting-to-happen may be perfect."
I'm pretty sure this is the first Free Stuff posting I've seen with the words "too dangerous" spelled out in it. Usually I have to find them subtextually. Kudos for the forthrightness, fire pit poster.
