You Can’t Change The Laws Of Physics

(My sister and I share a car. I have quite a few papers in there that I need for work.)

Sister: “Dude, when are you going to take out your papers?”

Me: “I don’t know. Why is the sky blue?”

Sister: “Because blue is the most scattered color in the light spectrum. Now, when are you going to take out your papers?”

Me: “I’m afraid that I don’t have a concrete answer to that.”
