We are twins

One in a million

You're my cookie

My every feeling 

When I am sad

you will cry

When you are scared

I will protect you

You're my twin

We think so similar 

But we are very different 

I am your twin

Which means I'll love you

My love last an eternity

no matter what is to happen

You're my twin

Together we can be unstoppable

I love your affection

Your every slap is perfection

We'll be happy forever

All we need is each other

What are we?

Twins
