[ Family ] Open Question : How to get along with your siblings?

I share a room with my older brothers and It doesn't matter how nice I try to be, we will still end up hating each other. I just want a normal relationship, they are 16 and 18 and I'm 14. Also I argue with my 16 year old brother the most because he is a know - it -all and that is why everyone hates him and he haves no friends. I just that we can't even talk.
