When we meet someone familiar on the street, firstly we greet by saying “Hi” and after that, we also ask automatically “How are you?”. The answer is usually “fine”.
This behavior was scientifically confirmed by a study: When someone else asks us, “what is new in your life?” we tend to give always a positive answer. We will not start to enumerate things that bother you.
Why are we behaving like this? Do we want to show how happy we are in our lives? Or do we want to protect others not to worry about ourselves?
The reason is a simple one: We do this for us because we like to confirm ourselves that we want to bring an improvement in our lives and to motivate us.
