Here's how the spelling homework scene went down in our house

Hank is brushing his teeth in the bathroom before bed. Mother is checking the spelling homework where Hank wrote: "Thermostat. A heater. I like to have a thermostat in the winter."

"Hey Hank, a thermostat is not a heater. You can look up the definition in the morning and rewrite your sentence."

"I am NOT. I'm leaving it."

"Hank, you're going to change it."

"I am NOT! Our teacher said she wants us to LEARN FROM OUR MISTAKES!"
