I have many reasons to wonder if my mom suffers from NPD, but chronic interrupting is one I didn't give much credence to - until now. She'll ask me a question, and before I can get the first two words out of my mouth to answer, she either answers FOR me or hammers me with another question. I don't know if it's a nervous habit or learned behavior or what, but it drives me absolutely nuts. She does this to my husband, too, but I've never heard her do it to anyone outside the family. What gives?
