Flash Fiction - A woman knows

Today, I thought I'd share a little seventy five word story, hope you enjoy!

“I’m not surprised. I knew this day would come.”
“You knew? How? I was so careful.”
“A woman always knows when her man is cheating…”
He chewed his lower lip. “Honey, your just imagining things.”
“Should have told her not to call the house…she left a message. You didn’t pay her last week.”
He cringed. “God, no! It isn’t what you think.”
She smirked, “So how many boxes of Girl Scouts cookies did you buy?”
