Who likes taking pictures of themselves

The story of one American Forum:
So much in love Joanna and John. John went into the army, they wrote long letters to each other. She promised to wait and make it a night after a fantastic muster.
When John came back, she kept her word.
In the morning Joanna says:
 - You know, John, when I was lonely without you, I put the camera on the self-timer and photographed. I wanted to please you a photograph of his army, but not solved, yet intimate photos, you could not understand. But now that we're together again, let's go to print them.
They printed, and since then has not seen.
QUESTION: Why?
