I don't know how anyone can think a sunset is sad, unless it's because a sunset isn't a sunrise. But if it's a sunset, how could it ever be a sunrise ?

In this way or that way,
As it may happen or not happen,
Sometimes  succeeding in saying 
    what I think
And at other times saying it badly
    and with things mixed in,
I keep writing, inadvertently,
As if writing were not something
    requiring action,
As if writing were something that 
    happens to me
In the same way that the sun reaches
    me from outside.
