nearly five years old my nephew plays with a stethoscope a fully functioning auscultatory device not just some toy of unavailing plastic and purposeless rubber lost to his imagination he holds the chest piece against my sternum the diaphragm cold even through my shirt making me pull away momentarily out of instinct or habit even though it is not needed he sits listening concentration tight across his brow with very real concern as he informs me that he can't hear anything that i must just have no heart at all
