A Martian's view on love

This is a poem written through the perspective of an alien viewing human interactions of love. It is inspired by a sector of poetry called 'martian poetry' which gives perspectives of human life through aliens.  This should be  cryptic so it shouldn't be easy to grasp. Will probably do another post explaining it at some point 

Two-headed creatures share a heart,

But stumble on each other’s limbs,

When their babies are vibrating happily,

Something strangely appears to be wrong.

Then the disturbances stop; together they make

Bizarre noises until they rest their eyes.

Now their heads depart, and delve

Into private fantasies, free from conflict.

Their eyes reluctantly open, but soon they

Assume their customary smiles.

Weirdly enough; they celebrate all of this,

with extortionate paper and glitter

Exchanges of the same dusty words and withering flowers,

But everyone seems equally impressed.

Apart from the Others whom lack attention so

 Instead use their thumbs to communicate

Whilst they go off in pairs and celebrate misery,

 The Others wish for the same pain!

They watch films about themselves

Whilst they indulge each other’s faces

The one-headed creatures stay at home,

Dreaming dreams to which replace with.
