Before I built a wall I'd ask to know
What I was walling in or walling out

Dr. Bill, they may not make sense in the literal sense of moving the stones out of the fields, but I like the sound of them in a more figurative sense. Y'know, don't build a wall between yourself and another person just because of a prejudice or a stupid fight or a perceived slight, but know what the other guy's about before building said wall.

My farmer friends in Saskatchewan tell me that there are plenty of stones there, too. You have to stop the tractor and get them out of the way. Or so I hear. Never done it, myself!
