Ditto what everyone said.
Your example sounds like the character's very realistic, which I like. I can picture someone who would act like that, it sounds normal given the circumstances - change of status, false security shattered when surrounded by a different kind of people.
In fact, I don't believe anybody can act the same in all situations. Because we're not quite these nice, perfectly logical and balanced beings - not only are we unable to do the 'right' thing at all times, we are unable to do what we think characterises us in all situations. And that's because the self is always growing and changing through circumstances and life; you could say we are many different things at once, we have the potential to become a lot of things and there are so many opposites in us that our growth is practically just reconciling those tendencies and developing them harmoniously (if you're lucky, that is

).
That's completely off-topic, but I felt like rambling. Imo it seems like you're taking the best approach, CaroGirl, so good luck with it.
