Tedious

"You all hungry? The Reverend took a long time unwindin’ this morning, he’s not usually so tedious."
Tedious means boring and continuing for too long. Calpurnia's observation about Reverend Skye disguises the fact that he has a lot on his mind about what has been affecting his community. He is worried for Tom and his family, and is trying to stay composed and strong for others to take confidence from him.
