Testo Cipher

Where is written that we belong together?
I distanced myself from me forever
Nothing is too little to live off
A little bit is too much, still not enough

I considered you necessary and absolute
But what, when we part?
There's no substitute! What will you do without me?
It's my choice and you have to agree

Even my heart beats today
nothing's forever and ever
Even I stand on the floor now
nothing's for ever and ever

Come and see for yourself
nothing's forever and ever

Don't be so arrogant to think you dominate
remember, we're two, we should collaborate
You are dependent on what I define
So take me as I am, or I take what's mine
