A reference to Pink Floyd, “Just another brick in the wall”.

I also look at the picket fence (with its connotations of the colonial, suburban, older person behind it), which has a tendency, just like concrete block walls, to be tagged.

When a fence is tagged and painted over and over again, we lose a more and more each time. To some those words, now lost, were as important as the clean slate of others.

Postscript - who will have the last word?
