From Eugenes point of view he is tired of Kate nagging him. Hence the sarcasm in the quote “You said yesterday , “I told you a hundred and nine times not to leave your things around the house.” From looking at Blanche’s input we can also tell that Eugene is being sarcastic or “smart” towards Kate by the quote “Don’t be fresh to your mother , Gene!”
Kate is trying to convince Keller that Annie will be good for Helen.
This would be Professional. This person does not show any sign of aggression or anger in this passage. This person isn't using the passage in a funny or sarcastic way and brought up the fact that they would like to work with the company in the future. He told the company he appreciated the time they gave him making this very professional.
Some quotes about forgiveness in The Kite Runner would be :
-“It may be unfair, but what happens in a few days, sometimes even a single day, can change the course of a whole lifetime."
-“And that's the thing about people who mean everything they say."
-“There is only one sin. and that is theft."
Hope this helps.
