“To paraphrase Oedipus, Hamlet, Lear, and all those guys, "I wish I had known this some time ago.”
“I was rich in those days, for a week I had everything. I wish I'd known you then.”
“I wish I had known that secrets get stronger over time.”
“I wish," he said, "I had known at eighteen what I know now - that there are some things on which one does not compromise.”
“Sorry," [Hamlet] said, rubbing his temples. "I don't know what came over me. All of a sudden I had this overwhelming desire to talk for a very long time without actually doing anything.”
“Wish I had known what seemed so strong has been and gone.”
