There is a misconception that a person who is good at talking to others always has 1 stories to tell and is full of jokes. In fact , most people want a two-way dialogue with interaction ,not just one person talking the whole time. A good way of creating good dialogues is by asking questions in a 2 way. For example, questions like “Do you live in London?” can be answered with a simple “yes” or “no”, which is not good for breeding conversations. But if a person asks “Where do you live?”, there is scope for a longer and, 3 , more interesting reply. This is what is called an open-ended question.
