The other day, my daughter Eliza was in a store when a woman approached her.

“You know who you look like?” the woman asked. “That girl who has been all over the news. Amanda Knox. You know, the one who was in jail in Italy for murdering her roommate.”

Eliza and I agreed that is a textbook example of a situation in which the ambivalent “thank you…I think” works perfectly. At least, that’s how I felt back in the ‘90s, when people told me I reminded them of a skinny version of Monica Lewinsky.
