Hello! Please remember that my response is for information only, we are not establishing a therapeutic relationship.
Nothing that you said sounds inappropriate to me --it just sounds like she might be more intelligent, more outgoing that other kids that you've encountered.
I know that the independence and obvious selfishness (as we get older we try to hide it a bit more) can be downright annoying, but really children feel the freedom to express themselves and their emotions without hinderance ---until they learn social/cultural norms.
Her fortitude is great, hopefully she will carry that part with her as well as learn how to ask for help when appropriate.
