if you live in the same house and have since birth and you concider yourself to be proper brothers and sisters then why would anybody challenge that.
i have a brother and sister they are mine and i love them very much, my brothers dad died befor he was born so apparently according to some people that invalidates our relationship as apparently we are only half brother and sister. i didnt even know we wernt concidered as such untill i was a grown up and would have been very hurt if it had ever been said to me,hes my big brother and thats that as far as we are both concerned.
equally as such all my children have been brought up as siblings since they were born but because one of them has a different dad people think thats ok to single one of them out as only a half sibling.
its usually formal paperwork or people who are putting a negative slant on what they are saying that do this and it really bugs me.things like 'he's only his half brother' usually said with in hearing of the kids.
its different if the child decides when there old enough to understand that they wish to use these terms.but why on earth do people think its ok to provide this family sepperation as a point of principal. i can understand it if they live in different houses or havent been treated as brother and sister and yes some brothers and sisters have different dads or mums but to my way of thinking that shouldnt impact on there ability to not only have a full and loving relationship with each other but that relationship should be able to have just as much validity to it as brothers and sisters with the exact same parents.
rant over now, so is this reasonable or not
