Bittersweet

Blood thundered in his ears
with the smell of must in his veins
while he kept digging further, further

As his hands ached in desperation,
his nails wedged deep apart with earth
while he kept digging further, further

For that vinegar tongue
behind sugarcane teeth
he kept digging further, further

'Till his mudsoaked limbs
reached the topsoil above
