"Suh" What

Was I the only one who noticed Tom Robinson said, suh alot. I think it was suposed to be sir, but its just the way he said it. So before I said the book was hard to read, as in it just kinda dragged on. Now after I have read 19 and 20, it has gottan alot better. It becomes somewhat clearer. And what happened to Boo, at first that was all the book was about now he isn't brought up but once in a comparison, to him and Mayelle. Oh well, and if you didn't notice or get it the title was "Suh" What, as in, Say What, but since Tom said suh, I used suh. Oh well, if you got it you got it. If you didn't you didn't.
