It is not that simple. I had periods when I did not really wanted to talk and strongly prefered when the other person talked more. I liked listening them during those periods.
Conversely, when I was socially isolated long term, people listening to my flood of monologue were God send.
It all depends on what whose needs are at the moment.
It's not transactional like that. You know when you are with someone for whom "listening" is just another word that means "waiting to talk again," or when you're just a receiver for whatever they want to talk about.
Ah...transactions...that get's me thinking...someone needs to create a cryto-coin for this ("listencoin"?) which you receive by listening and then can spend to get other people to listen to you...
I think GPs point was that aiming for parity in time talked allowed him to filter out people who wouldn't listen to that flood of monologue when it needed to happen.
