The Seasons of Love: Love Pitters; Love Patters

Love pitters;

Love patters,

Like rain drops

Falling down,

Watering the parched soil

Of the earth's desert lands

Where there is little rain

And wells often run dry.

Hatred, not love,

Appears to reign,

But it only lasts for a time.

Love always wins in its season.

Such are the seasons of love.

What are the two seasons of love?
