This is not an excuse, but I want to preface that the following exchange took place while on route to school. Getting out the door had been a circus-like endeavor and I was trying to focus on the nearby elementary school traffic. I can only do so much.
Full Speed: “Mom, what’s on Mars?” 
Me: “There’s sand and desert.”
Full Speed: “Are there houses?”
Me: “No.”
Full Speed: “Do people live there?”
Me: “Not that we know of.”
Full Speed: “So you’re saying we don’t know them. Are they strangers then?”
Me: (exasperated tone) “No, they aren’t strangers. No one lives there.”
Full Speed: “So, there are houses, sand and desert but no people?”
Me: “Sure.”
I can blame the faulty government or our school’s curriculum. but really my children’s education is being threatened by my own low-threshold of exasperation. I sometimes say what I say just to get through my day. Houses on Mars, Easter Bunnies who reside at the Holiday Inn, who knows what I will say next?
