Love was spring
when feelings bloomed
as we first said hello
and looked into each other's eyes.

Love became summer
when passions rose
as we held hands
and said our vows.

Love turned to autumn
when we fell apart
as things went sour
and we just can't stay together.

Love changed to winter
when the nights grew cold
as we traveled life's road
without each other.
