half, step or full blood

[Roseblum15]

I began thinking about this tonight, I hope that this post makes sense.

I have one half-brother who is the light of my life basically. Then I also have another half-brother and half-sister who I have never seen they basically don't exist to me.

So what I am wondering is should the labels like half brother, step brother or just brother come into play? or should they always just be called your brother?

Then how does it go if you have real blood siblings and then others from the split marriage. Do the blood siblings mean more to you than the others?

Just wondering what others think of this...
