Carpenter's Gothic Q&A: Pages 101-113.

Some questions:

• Paul is on the phone trying to convince a "grand plan" of his to Bobbie Joe (Reverend Ude's son) regarding how to get his dad a great platform to become noticed and likable. In the end, Paul is just simply being the Paul we are learning to dislike -- selfish and money hungry.
• Paul picks up the phone talking to Bobbie Joe saying how he just had this breakfast meeting with his staff.... LOL yeah big breakfast meeting with himself in his kitchen and his wife he takes advantage of, what a staff. Also how Paul puts a huge weight on Liz to pick up the phone calls all day as he's out on his ass doing what exactly? Making connections, right. 
• In my opinion, as much as Paul has more patience and a less negative tone with Bobbie Joe, Paul speaks to both Bobbie Joe and Liz in a very belittling way. He gets aggravated when he needs to repeat himself to Bobbie Joe for certain spelling errors. And from the beginning of the book, we've learned quickly that he's a rude and arrogant man that takes advantage of Liz's kindness and her money.
• I think Liz purposely gives him the chipped cup even when she doesn't mean to. If Liz can have control over something for a change, might as well give her husband the broken cup with the chip in it and give herself a nice, well put together cup lol :) On a more symbolic side, the chipped cup can represent Paul himself; he isn't perfect and has these faults/chips in himself.
• I'm not sure if the page of scribbles is Liz's novel but I don't think it is.. I think the page of scribbles is Paul's paperwork.. Obviously not important enough to him yet he's constantly saying he's got this big thing in the works going for him and Liz and constantly puts pressure on Liz to answer his "very important" phone calls and be very organized with them.. ironic.
• Paul wants Liz to write the letter as the voice of Reverend Ude's "dear Christian mother" because he knows his tone and mannerisms are very harsh, rude, nasty, and arrogant. He wants Liz's "nurturing" and "sweet" undertone. I'm not sure of what the significance of this plot development is but I can only guess it's a set-up for future arguments that might be bigger and more serious later on in the story.
