The snowflake, like so many other snowflakes out there, thought he had found the one:

He and his lover danced together in the sky,
In an icy interlocked embrace,
...They were falling in love,
but they were also falling...

...They did not 'break up' per se, but his lover broke - shattering and melting as she hit the ground...
...whilst he landed softly in the snow -
his form quite intact.

His friends tried to console him, saying "There'll be others...", to which the snowflake replied:

"Perhaps,
...but no one quite like her..."
