broad strokes

Me: [to the Big Girl who has just finished gleefully singing an incredibly violent song about a hawk dismembering a snake] um....
Boo: Hmmm?
Me: So, is that what you're learning in school? About hawks ripping out snake intestines?
Boo: No, silly, BBB (Best Buddy Becky) taught me that!
Me: Ah!
Boo: She also taught me about "broad strokes"
Me: Broad strokes?
Boo: yeah, like how sometimes things are big and clear
Boo: and sometimes they're little and take alot of looking
Me: Really?? BBB taught you that?
Boo: Well, I already knew it but she thinks she taught me so i let her think that.
Me: Ah....
Me: I love you.
Boo: i know.
