I dated a guy once whose parents asked he and his brother questions when they were kids and then wrote down what they said. I always thought this was a cool thing and the insight gained from how my kids respond is both hilarious and at times very enlightening!
Me: "Leif why is the sky blue?"
Leif: "Because that's the color it's supposed to be."
Me: "Skadi why is the sky blue?"
Skadi: "It's NOT BLUE, it's YELLOW!" (See what I mean... this says so much.)
Leif: "Did I get it right?"
Me: "Yes, I guess you got it right."
Skadi: "GUYS! I said it's not blue, it's YELLOW!"
Me: "Okay Skadi. Leif, why does it rain?"
Leif: "Well see first the clouds get full of water and so full they are about to burst and then they explode! And when they explode, the water comes out as rain called evaporation."
Me: "You mean condensation, right?"
Leif: (Breaking into song.) "The water travels in a cycle yes it does... the water travels in a cycle yes it does, it goes up in evaporation and comes down in condensation - yes mommy! You are right, condensation!"
Skadi: (Not to be outdone in the singing department...)"Old MacDonald had a farm EIEIO..."
Me: "Leif where are you going to live when you are a grown up?"
Leif: "Is elephant meat a protein? I think it's a protein. Is it a protein mommy?"
Me: "Yes, elephant would be a protein, but I imagine it would be really tough."
Leif: "Well I want to hunt elephants this afternoon and if I catch one you can cook elephant meat for dinner, okay?"
Me: "I think you would have to go a long ways from home to hunt elephants."
Leif: "Nope, just to Antarctica for snow elephants."
Me: "Skadi what is your favorite animal?"
Skadi: "SNOW elephants!"
Me: "Leif, what is your favorite animal?"
Leif: "Bears cause I saw one remember last summer in Alaska."
Me: "Yep, we saw bears."
Leif: "A bear would eat a snow elephant."
Skadi: (Screams.) "NO YOU CAN'T EAT MY FAVORITE ANIMAL!"
Me: "Ok, no one is going to eat a snow elephant."
Skadi: "I have a baby in my tummy."
Me: "Nope, only mommies get babies in their tummies."
Skadi: "YES! I HAVE A BABY IN MY TUMMY!"
Me: "What's the baby's name?"
Skadi: "Little baby."
Me: "You could name her Skadi Jeanne."
Skadi: "I the ONLY Skadi Jeanne."
Me: "You are right about that."
Leif: "When Niranjana and Cate have my babies, they will have twins like Ms. Amanda and we will all live at our house with our babies."
Me: "Yikes. I guess you finally did answer my question though."
