A couplet is a pair of lines that rhyme. Usually both lines have the same meter. A couplet expresses a complete thought and can be funny or serious. Some poems are made from several couplets put together. 

The couplet form suits a love poem, of course, because the pairing of the two rhymes, so close to each other on successive lines, mirrors the coupling of the two lovers.

The birds are singing

The daisies are blooming

The sun is getting up

On this early morning

The dew is rolling

The branches are dancing 

I whispered to them

Hello my happy garden
