Jenny has a father in Boston who has laughing blue eyes and a beard. She will never know this, however because he will always be just "donor" to her. She imagines he was a spy captured by enemy soldiers and that's why he never comes to see her. In fact, he makes people happy playing beautiful music on the piano. Jenny will never take piano lessons because nobody knows how much she would love it if she had the opportunity.
Jenny has a Father in heaven who loves her, and she loved Him too until she was taught that He didn't exist and that people who believed in Him were ignorant and hateful.

Any sadness Jenny has is her own fault because she's not trying hard enough.
