Forgive me (9)
Well we know now that the members of this household ask for forgiveness, and communicate. That's a good sign. Even though the speaker has wronged someone he lives with, by eating their plums, he's nice enough to leave a sweet, sheepish note. He could have left one that said something like, "Ha ha, no plums for you, sucker!" Instead, he shows obvious consideration and care. It not only excuses the speaker from eating the plums, but also shows that he's thinking about the person to whom he's writing, even though she's not awake right now.
