In chapter 7 pg 58 Jem says '' When I went back they were folded across the fence ... like they were expecting me.'' This is talking about how he found his pants fixed and hanging over the fence. This shows grace because Jem did not deserve to even get his pants back, yet Boo Radley fixed them for him and left them there for him.
In chapter 3 on page 24 Walter and Atticus talk to each other like to grown men even though Walter is a child. Walter proceeds to say ''Reason I can't pass the first grade, Mr. Finch, is I've had to stay out every spring and help papa with the chopping.'' This shows grace because even though Walter is a child Atticus still decides to treat him as an adult or equal to himself.
In chapter 8 on page 71 Atticus asks Scout ''Then who's blanket is that.'' Atticus was referring to the brown blanket on scouts back. Scout claims to not know where the blanket came from because she was watching the burning house while Boo Radley put the blanket on her back since it was freezing outside. This shows grace because even though Scout has tortured Boo he still decided to help her when she was cold.
