Poco se sabe (we don't know enough)

This poem is really wonderful but the little problem is tha it's written originally in spanish, so I'll try to make a reliable translation but if you like, you can check the original one in order to compare and correct mistakes. Thanks

I didn't know that don't having you

could be so sweet as calling you,

to make you come although you don't,

and there isn't but your absent

as hard as the hit I had in my face thinking about you
