Context

“Everything within me was seething.
"You are now no longer cruel, but cheap," I said, clearly and distinctly, accentuating every word.
"You have already written that in your letter," Wanda replied, with a proud shrug of the shoulders. A man of brains should never repeat himself. "The way you are treating me," I broke out, "what would you call it?"
"I might punish you," she replied ironically, "but I prefer this time to reply with reasons instead of lashes. You have no right to accuse me.” source
