“If you don't know why, I could never explain it to you.”

“I don't know why
I love you like I do
I don't know why, but I do.”

“I wish I could be near you to hold your hand and explain in some detail the reasons for my death. I know at this point that it has fallen upon you in a way that I wish would not have happened. I wanted to explain to you the night before I left New York that I was really going to Spain, and the reasons why.

all the time you keep believing,
but I don't know why

Even when the sun is shining

but I don't know why
you won't say goodbye.”

“I don't know why nobody told you how to unfold your love
I don't know how someone controlled you
They bought and sold you.”
