Mmmmmmmmm ; -)

At, learners, I must apologise to you ;-) ...for capitalising the word
IMAGINATION. I appreciate that the change alters the spareness in the
wholeness of what your writing conveyed in both the smaller and larger
domains both the invisible and visible.

You know, sometimes reading here breaks my heart and numbs my mind...why
is that?
