After a 12-year-old's lesson, I was talking to his mother before he finished packing up and came out of the room, and I was praising his newly found attention to detail (12-year-old boys + detail work usually = something that doesn't happen).
He came out, and I told him I was saying nice things. His mother said, "She says you're doing really well with detail work, is that right?"
Student: *grins and blushes and shrugs*
Mom: A man of few words.
