I don't know why it's the same reason why you like some music and you don't like others. There's something about it that you like. Ultimately I don't find it's in my best interests to try and analyze it since it's fundamentally emotional.
I didn't have any role models really. My best friend was a dog. My mum and dad saved a dog from the gutter and that dog was my brother before Jesse was born. Sami was his name and he was my role model.
