Eleanor, who is supposed to be doing math: "Mom! You know how you get brain lock sometimes? I totally just got brain lock and can't remember a fact."
Mom: "Yeah. Yeah, I get brain lock all the time. What is your missing fact?" [I'm thinking it's a math fact.]
Eleanor: "I can't remember where Plimouth Plantation is."
Mom: "Uh, why do you need to know that right now? Aren't you supposed to be doing math?" [Wondering if she is supposed to figure out the area of Plymouth Rock or something.]
Eleanor: "Yeah, I am [supposed to be doing math] but it just popped into my head and I just have to know where it is right now."
