A few weekends back a girlfriend and I were at the beach for our first swim of the summer. It was an overcast morning and the water looked dark. We were trying to stave off the inevitable shock of cold water by discussing our chances of getting eaten by a shark. She turned to me and said: “Any self-respecting shark would take one look at me and say: Geez, I’m not that hungry.”

A real friend doesn’t lie about her weight. A real friend understands that a woman’s weight can be central to her mood: thin = happy, not thin = grumpy. My bathroom scales are an electronic slab of nastiness hell-bent on destroying my morning.
