Ok, are people seriously griping about how Sarah Palin ate a slice of pizza? (She *gasp* used a knife and fork instead of her fingers.)
Let's just be honest here. If she'd used her bare hands, someone would be saying that she lacked class because of that. No matter what she does, it's "wrong".
Personally, I usually eat pizza with knife and fork, these days. I don't think I did when I was younger, and I don't have to have utensils even now, but I do prefer it that way. It makes less of a mess-- no greasy fingers, smears of tomato sauce on your face, choking hazards of stringy cheese, etc.
Anyway, why should anyone care how someone else chooses to eat his or her pizza? Why does it matter? What is this? An episode of Seinfeld? ;o)
