Were you ever in a great and happy mood and then out of the blue you were flushed by feelings that caused a deep sadness? And you don’t even know why? That happened to me last Friday. We had great weather, I was happy and cheerful, and all of a sudden I had a song in mind that I did not hear for years. I love that song a lot but while I started singing it heavy desperation kicked in and I didn’t know why.
