For about 8 years now I have not gotten along with my younger brother. He is slightly less than 2 years younger than me.
He has become an ultimate Nihilist and we can't talk about anything without it leading to an argument. We don't share similar taste in games, music, Tv/Movies, Books whatever.
Its made worse by he thinks every argument needs to end with his winning and me conceding and that I am a total idiot and he knows everything.
The only subject that he likes to discuss in world war 2 , Imperial Era, World war I.
