Well, I'm Italian, but my family isn't stereotypical. I mean, I only have one sister and we don't yell or throw pasta at each other. My mother doesn't even have a secret spaghetti sauce recipe.
I can see that you are a true historian because you really always ought to ask that question about anybody at a different place or a different time: What's the same and what's different?
If you really do want to be an actor who can satisfy himself and his audience, you need to be vulnerable. You must reach the emotional and intellectual level of ability where you can go out stark naked, emotionally, in front of an audience.
