These——-> ” ”
Or simply writing “not my original idea.”

Thank you. My fingers and my brain weren’t on the same page, I meant what punctuation marks should be used.
What if you don’t want to send the message that the expression Bull in a china shop is an incorrect terrm for Trump, the way you don’t think Burquini is the incorrect term for the so called item?

What if you don’t have any more characters left to add “Not my original idea”?
