Brother and sister often live in the same room. Is this normal?

Here you are. . . . . . It's hard to say that brothers and sisters with deep feelings should be normal, but generally speaking, they will not be so close when they are old. After all, men and women are different. In another case, brother and sister may have a special relationship because they are curious about men and women from an early age. It is not impossible until now, but we must be careful not to doubt our husband easily. From the dialogue and eyes between brother and sister in daily life, you should be able to see what kind of relationship they belong to.
