The sonnets are almost all constructed from three four-line stanzas (called quatrains) and a final couplet composed in iambic pentameter. This is also the meter used extensively in Shakespeare's plays.The rhyme scheme is abab cdcd efef gg. Sonnets using this scheme are known as Shakespearean sonnets. Often, the beginning of the third quatrain marks the volta ("turn"), or the line in which the mood of the poem shifts, and the poet expresses a revelation or epiphany.
Should love be sacrifice or freedom's act?
Or maybe we need both to make love true?
No vows and yet as if there was a pact
That makes our pillows and duvets like glued.
Is sharing our affections for the weak,
Though often it does happen through the Web,
That string which even when we rarely speak
Gives us the strength to make another step?
However, if it is inertia just
Does that mean we deserve to be laughed out?
When love's cooled down and we've forgotten lust
Can we still claim that our love is stout?
So give me days and nights, take mine, and so
We will go on, will give, but never owe.
