fill up the blanks

In the childhood
when my teacher
gives me
task
to fill up the blanks.
I feel delighted
and fill up the BLANKS
with appropriate words.
But
today
I am searching
the appropriate
WORD
which could probably
fill up all the blanks
in the ocean of my heart
my search for the word
is never ending
and timeless
probably
till that day
last leaf

on the earth will drop.
