I was in several gatherings with very talkative people. Sometimes when that happens I find myself responding by talking a lot as well.
This time I listened and when possible responses came up I brought my attention back to the speaker until the end of the sentence or story. If my response or question was still something I wanted to say at that time I did so. I felt free to not chatter in return.
Something about waiting to speak about things I was really wondering about made the conversation more spacious. I felt more relaxed afterwards as well. It seemed to bypass the conversation headache that I sometimes get after that type of gathering.
It's a tiny practice but interesting stuff is popping up.
