The fall of the stars

Once upon a time, in a world so divine
Four little girls, their stars aligned
Playing games, watching shows, laughter in the air
In their little group, they had not a care

But as the seasons changed, so did their game

Anger and sadness, feelings ran high
Two little girls, left alone to cry

Time moved on, one came back

But one stayed away, found someone new
Three together, one feeling blue

An invitation extended, a hand reached out
One more joined, leaving no doubt
But one remained, self-excluded and alone
She walked away, into
