In how much time would two strangers begin to talk informally?We often meet strangers in our day to day life and have many conversations with them. Very few among these strangers later comes under our various classification of acquaintances within our head and even tend to become our best friends.
But most of the time we speak formally when we meet strangers because of courtesy and manners we have been taught from our childhood. But have you ever thought about how much time it takes to speak informally to someone we meet.
It may vary from person to person according to their nature and behavior but still, what would be the approximate time within which a person may begin to speak informally?
