Valentine Poetry Greeting: How necessary is it to remind A loving couple that they are...

How necessary is it to remind
A loving couple that they are in love?
Perhaps a well-placed word might pierce the rind,
Penetrating hearts that dormant prove.
Years accumulate like fallen snow,
Vast fields of understanding, thick and cold,
Taking a risk that else they might evade,
In search of pleasure even angels seek.
Need comes slowly, like a warm spring rain.
Except one sing, the song must be in vain.
