Yea, I knew that. Well, I guess what I wanted to confirm was the meaning of the sentence. "It is a fact that I used to have no considerable relation with my brother(in-law)." That's my translation of the sentence. Correct me if I'm wrong.
What I'm wondering, is if this "relation/connection" that she speaks of it referring to a friendly relation like a brother and sister getting along, or referring to the connection of being part of the same family(Once their parents had married). It has a dual meaning, which I thought, might be clearer on the Japanese end.
Also, I'm under the general assumption that the Japanese usually refer to brother-in-laws as Ani-san, Ani-sama, etc. Does calling them Onii-sama reflect an increase in affection towards the brother-in-law? In other words, does the speaker now consider the brother-in-law as a true brother to be counted as part of the family?
