If I had written

 Last picnic

It might have been stated differently:

Let this picnic

Not ever be our last

Instead

Let’s hope for many more

A loaf of bread

Some grapes & cheese 

A simple lunch

Please

Unfold a quilt & 

Let’s languish by the side of the sea

Wander & wonder

Amongst bright orange

And yellow leaves

Winter is sure to come

And with warmth of a fire

And your love
