Girl interrupted at her music

This time I read the title of the painting: "Girl Interrupted at Her Music".
Interrupted at her music: as my life had been, interrupted in the music of being seventeen, as her life had been, snatched and fixed on canvas: one moment made to stand still and to stand for all the other moments, whatever they would be or might have been. What life can recover from that? ... the entirely credible yet unreal Vermeer light. Light like this does not exist, but we wish it did. We wish the sun could make us young and beautiful, we wish our clothes could glisten and ripple against our skins, most of all, we wish that everyone we knew could be brightened simply by our looking at them, as are the maid with the letter and the soldier with the hat. The girl at her music sits in another sort of light, the fitful, overcast light of life, by which we see ourselves and others only imperfectly, and seldom.-Susanna Kaysen, Girl, Interrupted
