If you say no and it's ignored, continue saying no. Don't give in. Dr. Kinsey refers to this as the broken record method. "Set the boundary politely and tactfully in the way you ordinarily would. If you're feeling generous and depending on how [they react] to the boundary, remind them that you already responded and would appreciate that they respect your wishes," Dr. Kinsey explained. "If a firmer approach is necessary, simply state, 'No.' Say 'no' again. Repeat 'no' once more. Continue saying 'no' confidently, unapologetically, and without hesitation until the pestering stops. If the pestering never stops, exit the conversation."
