What's a meta phor?

Or, that's a similar simile

 

The evening dark comes now, my love,

As if it were the close of day,

The stars so bright and small appear,

They seem like suns so far away;

The night so very black, my love,

I cannot see you overmuch,

Nor even reach to hold your hand

Except for when we touch.

And still the worlds spin madly on,

As planets whirl through outer space,

We hurry on, we hurry on,

As though we'd win the human race.
The wind howls on, the rain is wet,

Almost as if inclement weather -

O! May we two kiss now, my love,

As humans osculate together?
