Annie sure had a culture shock in the South...
Annie must have had a terrible culture shock when she arrived in the South, so alien from her home. I think she had to strain to understand that southern accent that people in Alabama speak (and the Kellers, I think had trouble understanding poor Annie since she seemed so alien to them also).
I've read that Annie felt awkward, homesick, and uncomfortable in the South and people in the small town of Tuscumbia looked at her funny and snickered at her accent and mannerisms. I also read that she hated the awful heat down there and sometimes was nauseaus because of it.
I kind of laugh when Annie is shocked and insulted when Arthur insists on carrying her down the ladder; that certainly was a weird, not to mention sexist custom that sure took Annie aback.
I read that Annie was glad and relieved to return home to the North where she felt much more comfortable. I was happy for her also; I'm glad she didn't stay in the South permanently; that would have made her too miserable.
