Phoenix

I have a three year old brother named Phoenix. For a while I've been finding it quite odd that he wants to be bigger than everyone, lies blatantly, and believes that pink (along with other things) is for girls and he's a boy so he has to hate it. Now I have no idea how these things came to him, my family certainly doesn't teach him those kinds of things, so how does he get those ideas? He even one time screamed at me for calling him my baby brother because he's a "big boy me no baby!!" What's wrong with being a baby? I don't know but he sure seems to. I don't know how or why we do these things but it seems like it might have to do with the subconscious. Ill look into it and let you know.
