I didn’t know (generally) people from the same parents do not have similar family name in Afghanistan

Me (sitting in the office talking with my colleague): hey guys do you know who is “P” that the young students love him so much? Is he really honest in his political claims?
H (the colleague who I asked him): you shouldn’t ask me this question!
Me: why?
H: because he is my brother.
Me: OH! You guys have the same mother? (I was surprised since here having the same mother but different father is some thing very rare, because this would be the consequence of dead husband or divorced women, and there are strict rules for these cases. I’ll write about it later.)

H: NO! We are from the same parents!
Me: what? don’t say nonsense! His family name is “P” and yours “H” how can you be brothers???!!!
H: believe me! Ask others. We do not have the family name in Afghanistan. We have Takhalos (what do you want to call yourself)

And he was right. Now I see why people here just call each other with the first name. Just like the old times in Iran, (that I haven’t seen!) I do not know how it is in other parts of the world. It was really cute! It seems the concept of having sort of family name had came for the people who were applying for passport for immigration purpose.

Also here marriage is not registered anywhere! I was teasing my friends: “good! can I have as much as husband I want to? Who knows, nowhere is registered!” They were shocked and trying to explain me that of course the family knows you are married! (maybe that’s why the family and tribes have such strict (some times inhuman) rules against women.)
