The envelope had a four-cent stamp and no return address. Inside, a recipe card, stained brown and yellow from decades of use.
I recognized the handwriting even before I read the first line. My mother's cursive, looped and careful. The card for her Sunday dinner rolls.
I must have stood in the kitchen doorway for a full minute, just holding it. My granddaughter tugged my sleeve and asked what it was.
I showed her the smudges, the corner where the ink had bled from a drop of vanilla. I told her my mother used to bake these rolls every week, no matter what.
The card had been mailed from my sister's town, three hours south. She never called to warn me. She just sent the card, the way my mother used to mail cookies in a tin.
That night I set the card on the counter and made the rolls. My granddaughter helped me mix the dough while I kept my whistle on its lanyard, resting against my chest.
First day back after a week's leave. I didn't tell anyone at the depot about the card. I just drove the route, glanced in the rearview, and thought about how a single stained piece of paper can carry a whole life.
The rolls came out lopsided but warm. My granddaughter said they tasted like clouds. I think my mother would have laughed at that.
