I

I’m the yesterday

I’m the present time

I’m the tomorrow

I’m the daily journey

I’m the night

I’m the heat and the cold

I’m the wind and the snow

The clarity and the dark

Truly I’m humain
I’m all the feelings acquired unwillingly at birth

and all the errors brougth up by life

But mainly, I don’t have one only sense

And I’m not obvious
I’m the unavoidable change that arrives to everyone

And the endless peace that reigns in a heart

But not at all just any heart
Above all, a heart that has fallen in love

What am I?
