Siddhartha notes

Find theme, plot, characterization, central message, tone

Central message-- Don't be restricted by your culture or your parents or anything else. Finding out who you are is a part of life that shouldn't be avoided.
Theme-- Loss of self
Plot-- Leaving family to do his own thing. Whatever he wants to do, he now can without fear of backlash from anyone.
Tone-- The author leaves a lot up to the reader to decide (as explained by Dr. Preston). The attitude toward Siddhartha is understanding, like at one point the author felt the way Siddhartha does.
Characterization-- A lot of the characterization is indirect, told by Siddhartha himself. "How deaf and stupid I have been, he thought, walking on quickly." When he says this, we know that he is hard on himself. He is also intuitive, seeing that others fit in with the Brahmins while he maybe wasn't meant to.
Dr. Preston dared me to do this, so I'm just going to include that while he was reading the passage as it was projected on the board, I was reading along mentally in Cartman's voice and had a really hard time not laughing.
