1) In the Wikipedia entry on "mirror," I found:
"A mirror is used for inspecting parts of one's body which are difficult or impossible to see directly, such as the face, neck or the whole body. This may be to checkphysical appearance (including clothing, make-up, hair, etc.) or to control applying make-up, shaving, cutting hair, fixing one's tie, etc."
Did the author of this article think there would be someone who had just bought a new house, and found a strange, reflective object in his bathroom, who said to himself, "What in the world is this thing? Let me log onto the Internet and go to Wikipedia to discover what I could possibly do with this thing?"
2) I bought a bag of pistachios at a gas station today. On the back of the package, I found: "Allergy warning: This product contains pistachio nuts."
Is there some allergy sufferer out who might buy a bag of pistachios unaware that the bag would contain pistachio nuts?
