A secret admirer

Once upon a branch,
there lived a bird,
which sang songs nobody heard.
But nonetheless, being shameless,
he sang his poor heart out loud.
Be it sunny, rainy, snowy or something else,the musical chords seldom shut the fuck up.
Lost in his own world, barely anything mattered to him
—except on that fateful afternoon.
Struck by his loneliness,
no, not the lack of audience,
he stopped singing.
Just like that.
Silence prevailed for a few days,
before the brown ol' tall tree broke silence,
"I'm your greatest fan and you can't do this to me!"
