only a little light

on nights like this i know my exact worth
less than a penny and mighty dear at that
i've learned that all hopes and desires go splat
my sole life function is to provoke mirth
about my immense density and girth
i'm lucky i've got somewhere to hang my hat
and if i feel aggrieved well then by drat
like a hunted fox i'd better find an earth
so little time and then much less for joy
my part's been played and now i'm off the cast
the world will little note nor long remember
instead a bright and shining little boy
shall tell me that my efforts will not last
and all my light will fade to one last ember
