Friends co-creator Marta Kauffman has apologised for misgendering Kathleen Turner’s character in the series.Speaking on the BBC radio show The Conversation, Kauffman, who created the hit sitcom with David Crane, admitted that it was a “mistake” to refer to Chandler Bing’s transgender parent as a man.“Pronouns were not yet something that I understood.
