The ability to empathise with the other is the secret of rapport, modern psychology says. Many of us try to help others by listening and empathising with people who suffer. However, our effort falls short when it starts to consume us, when the other's problems are so overwhelming that we have to lose ourselves, give ourselves, out time, and our life to empathise. Most people stop at this point.
We want to continue our little worlds.
