Another Brick in the Wall

It's like I'm trying to talk to him, and he's a brick wall. And sometimes, it seems as though I can get through to him: sometimes, it seems as though there is a space where one of the bricks usually is. But the moment I try to get through in that space—boom—the brick gets shoved back in. So what do I do, well, obviously, I look for other openings. And I find them. But, again, the moment I try to get through—boom—the brick comes rushing back.
