My try as learner:

-o:gelmedin bugün nerelerde sürtüyon

 You haven´t come today, where were you wandering ?

-n:Mervedeyim,sen ne yaptın

I am in at Merve´s, what have you done ?

 -o:heee,

-n: sabah kimaçacak 

Who will open in the morning ? 

-oL: bende görmeyince geldiğini

Me too, when I did not saw that you had come (really not sure about this)

Here "de" is not in the meaning "too". Actually the sentence is uncompleted..and it means something like "seeing him/her not coming ..."

 kim açsın

Who will open?

notice that it is not "açacak" but "açsın" which indicates suggestion that  "who shall open" must be preferred, according to my limited English knowledge..

-n:birol

Birol (will).
