I liked being the answerer because I could just tell my full answer without anyone else interrupting before I finish my statement.
I don't like being the summary paraphraser because if the the person says something I want to add to I can not say my statement. I have to paraphrase their answer first. Which is okay too I guess. It's good to listen because you have a chance to learn by hearing other people's ideas.
Try using summary paraphrase after you listen to make sure you understand what your partner is really saying.
