I'd better shut up

When I want to talk,
do I want to talk something else,
and so I talk something else?
Or do I want to avoid this,
So I end up telling you that?
Or do I tell you that
because you don't want to hear this,
is what I feel?
Or because of your hints
that you'd rather, me tell you that,
than this,
this damn dark serpent,
out to strangle you?
