This is Gale's POV, simply saying how he and Katniss's relationship grew. Rhyming.
It started with a single thread,
A quick and simple "hi".
Woven together, thicker it spread,
As the days and weeks crept by.
More colors and lengths added to the mix,
Friendship's treasured touch grew,
Bound so tightly nothing comes betwixt,
A fabric of friendship renewed.
How many threads had been woven in
To a friendship never to be broken?
How thick had it grown, when,
It started with a friendship token?
It filled the sky, unbroken bond,
Not made by force or treasure
Forged by kindness, never gone,
A simple friendship pleasure.
But more and more it grew and grew,
Until more than friends remained,
But you left with him, so I am lost,
And nothing will stay the same.
