“Maybe I’m a little old for this dress?” I suggested tentatively as I made my way to the mirror in the little shop.I was in the artisans’ market in San Miguel de Allende, Mexico, where they sell everything imaginable—and quite a few things I had never imagined. I was wearing a dress that had been hanging on a rack outside a tiny shop in the market. It was in my favorite colors.I’ve been collecting “my” colors, various shades of blue and green. It started with the bracelets. I bought a turquoise one for a few pesos and then I found another one that matched. Then another. Then another.

And I also think it is why I am constantly buzzing through the artisan market, dipping into little shops along the way, looking for my colors. I’m like a bird feathering her nest. I bring back woven napkins and potholders and a bright blue apron with yellow flowers embroidered on the front. Peter is a regular at the chicken roasting shop where dozens of chickens turn on a rotisserie. When he takes too long fumbling with his pesos, the woman who roasts the chickens grabs the money out of his hand, takes what she needs, and returns the wad to him. She is not about to burn her chickens waiting for Peter.Today is our seventh anniversary and we are celebrating it in the best way possible—by living our life the way we do every other day. Peter ...
