We go together

I'm the black,
Your the white.
I'm the day,
Your the night.
I'm the stars,
Your the sky.
I'm the ice cream,
Your the pie.
I'm the mac,
Your the cheese.
I'm the pretty,
Your the please.
I'm the ocean,
Your the sand.
I'm the fingers,
Your the hand.
I'm the flip.
Your the flop.
I'm the soda,
Your the pop.
I'm the clouds,
Your the sky.
I'm the girl,
Your the guy.
We go together,
like 1 and 2.
You with me,
and me with you.
