This will be my favorite poem of the many masterpieces you have shared . I have been there several times

There is a longing for a lost innocence, a sense of loss hangs over memories which were once so alive and true with a promise never to vanish. I like the title for the ghost in this context represents a past that was loved, or past that has departed, or a past which you know is never going to be lived.

I don't know but its what this says to me...sad and pain for something which used to make you smile now you accept it as sadness with open arms.
