Alliteration used in the poem "Indian Seasons":
Summer comes
in a blaze of heat
with sunny smiles
and dusty feet

Then seasons change
to muddy roads
monsoons and mangoes
leapfrogs and toads

Spring is pretty
but short and sweet
when you can smell the grass
from your garden seat

Autumn is English
in red, yellow and brown
Autumn is Indian
whenever leaves fall down
