I think my attitude's different when I'm in the different places. I don't walk around in character. I try not to walk around with the accent, but those little things change you, whether it's your hair, your clothes, your shoes or a different silhouette. People absolutely look at you differently.
I was always amazed the way people would come in looking one way and transform completely to the point where I couldn't recognize their language, their accent, the way they looked, their hair, their face even changed becoming so inside of the character.
Language development, for instance, has a critical period that begins in infancy and ends between eight years and puberty. After this critical period closes, a person’s ability to learn a second language without an accent is limited. In fact, second languages learned after the critical period are not processed in the same part of the brain as is the native tongue.
It takes more time and effort and delicacy to learn the silence of a people than to learn its sounds. Some people have a special gift for this. Perhaps this explains why some missionaries, notwithstanding their efforts, never come to speak properly, to communicate delicately through silences. Although they "speak with the accent of natives" they remain forever thousands of miles away. The learning of the grammar of silence is an art much more difficult to learn than the grammar of sounds.
Long before there was discrimination against blacks, there was discrimination against white southerners. When large numbers of these country people moved north during World War II, they were aggressively excluded from neighborhoods, jobs, and homes - not because of their skin color, but their accents.
