a note
I went out early to get milk. When I got back this note was on the table. I will keep it forever because it is just so sweet and so Eva at age eight. I know I can't keep her where she is right now, and I wouldn't want to—she just keeps getting better—but responsible little notes about doing storybook childhood things? I could keep that forever.
write the date on the back so you remember when she wrote it. that's what i'd do.
