This look very interesting and I can see it having an effect on a relationship whether it is new, old, romantic or platonic.
My guess would be that it allows us to focus fully on one person and who they are, conscious of the fact that the other one is doing the same.
Nowadays I feel that a lot of the conversations that you have with people you meet or people you don’t know that well are extremely superficial. You don’t really care, or you focus more on the way you present yourself rather than trying to understanding who the person we are engaging with is.
Anyway I think ill try suggesting this to someone I meet. See if it changes anything.
