I subscribe to an email newsletter called Word Genius. A few days a week, it sends a word with its definition and examples in a sentence. As I've noted in another blog, when I was a little girl, the other little girls in my neighborhood loved to bully me for reading, and liked to call me the Big Word Mama as an insult. So be it.
A word this week was Insouciance. It means Casual lack of concern; indifference or Cheerful feeling with no worries.
Two examples of Insouciance in a sentence:
"I admire my partner’s insouciance toward traffic and other things that annoy me."
"On the last day of school, the children ran out of the building, riding high with insouciance."
I have decided that it's not ignorance that's bliss. It's insouciance.
And I long to feel blissful...
