A reverse poem. Read top-down, and then bottom-up.

======================

Goodbye.
Ending slowly,
Warming, glowing, crackling,
Consuming, covering, stretching slowly,
Flames curling around sickened trees,
Spreading, thriving, embracing all,
Hiding in twigs,
Waking infant,
Hello.
Hello.
Infant waking,
Twigs in hiding,
All-embracing, thriving, spreading,
Trees sickened around curling flames,
Slowly stretching, covering, consuming,
Crackling, glowing, warming,
Slowly ending,
Goodbye.
