The need to fill the emptiness

There exists in many of us the urge......the need.....to fill the blank spaces around us with things:  images, words, furniture, etc..  As Nature abhors a vacuum, so do the eyes of men abhor empty spaces.  Perhaps it is the creative nature of humans to see those spaces as opportunities for expression.  For instance, I feel an almost irresistible urge when I walk into my favorite Starbuck's to take a magic marker and fill the empty wall space with my poetry.  In my case there may be other issues involved as well, but I can honestly say to you that the vast blank spaces of wall there cry out to me to be filled.
