Active Listening is 2-way
Active listening, as I understanding it, means to give back information what I understood. This is valid for both sides of a discussion, the sender and the receiver
of a message.
As a sender, when my dialog partner provides in his/her words back what I told him/her, I have a feeling for what is understood so I can adjust something if I think it is necessary.
For me as an receiver, I know when I can give back what I undstood, my dialog partner and sender knows if he needs to adjust something.
In both cases it means working on the same issue and there can be no parallel processing of different things.
