Turning up the music and pretending the noises in the hallway are background noises in "Taking the Farm" or "Shine a Light"

Wolf Parade says, "And I'm content, I'm content, I'm content to be quiet/ Some will sink and some will get called to the light."  I'm sitting in my bed, quiet, in my room, and my parents are fighting about where my Dad put his inhaler.  He can't find it.  My mother says he needs to be more responsible with his medication, and he needs to put it away when he is done with it.  That is, he shouldn't leave it in the kids room, in their drawer, on top of their desk, etc.  My father yells back that he needs his inhaler, or he can't breathe at night.  And besides, where is he going to put it?  "In a fucking safe?"  Etc, etc.  The wailing in the background of "Taking the Farm" can't be distinguished from the wailing outside my bedroom door, so I'm quiet, content.

When I am cleaning out the grease traps at work, or emptying the friolators through the fry-filter, I still get comments that I am not smiling, or that I don't look happy.  Why do I need to have a smile on my face when I am covered in grease, and while I am filtering that, if handled irresponsibly, could give me third degree burns on my arms?  Those too are occasions for smiling and chipper conversations?
