dear thanks for your response..
i am not an expert but according to my experience and idea the sentence below

He should be brave and bold but not selfish to have mixed up with animals

is not relevant to your topic or you can say looks out of context because it does not contain anything regarding language and what looks to me in the precis is that language is the main theme.
the remaining part is OK .


well i have given u my opinion on my part,i does not anyhow mean either u r right or i am.
so just considered it as an opinion...

Regards
