Unconditional...what??

I went to see a show called "Sondheim On Sondheim". For those of you who don't know, Stephen Sondheim is one of the most brilliant musical theatre composers ever. His music is incredible. Anyway, they filmed him talking about his life and putting his songs in to fit whatever they were talking about in the dialogue. Near the end of the show he was talking about his mother. He never had a good relationship, but he just assumed that it was something that would resolve itself. Later in life (around age 40) he received a letter from his mother. She was about to go into open-heart surgery. The note read: "I want you to know, as I go into open-heart surgery, that the biggest regret I have in life is giving you birth."
I sat there for a minute just in shock - how could any mother say that to her son?? I was stunned. My mom and I don't always get along, but she's NEVER said anything even close to that. A mother's love is something that is irreplaceable. I was just shocked. After that they played one of his songs: Children Will Listen. I found it really touching that they played such a poignant song having to do with parents after finding out what his mother did. It just really touched me.
