Katherine "Katie" McLoughlin: He doesn't listen when he's this mad!
Nell McLaughlin: You know what they say: "Anger is just fear on the way out."
Katherine "Katie" McLoughlin: Nice try. He's not afraid of anything.
Nell McLaughlin: I don't know, you could scare the heck out of anybody.

Nell McLaughlin: When you were three, you climbed out of bed, unlatched the kitchen door, and walked outside. He found you in Lightning's stall. That horse was crazy, he could've killed you and you were laughing.
Katherine "Katie" McLoughlin: I don't remember that.
Nell McLaughlin: Yeah, well he does. Parents have this kind of... selective memory. Sometimes I think I can't remember what I did yesterday and then I swear I can remember every injury, every close-call, every 'another inch and they could've been killed' that ever happened to my children.
