discussing (or questioning) about a subject yourself? I had the same feeling, that in those last chapters there is much more to say. So I simply postet two thoughts that came to my mind hoping others would follow my example - and they did. I think everybody posting here does it - as Julie says- as a hobby and besides job, household etc. I think itīs a great privilege to have so many kindred spirits trying to do what they can to share their thoughts with us. So why not making the first move on your behalf? ;-)
