A dialogue is a continuous thing that lives along with us in each every communication that we make with someone else who is either near or far, it matters a lot or less. Conversation that we make from our childhood with our school friends, college mates, colleagues and especially with our parents, siblings make us to react for those things rapidly but when it comes to a person who is unknown and when we have a conversation with them for a while, we remember how to talk to them and get the response positively (Nightingale, 2000). When we analyze, we forget the basic way that these things could be even followed with all the people whom we are talking daily. If we are always with sweet words with people who are close, we might get hurt. So at times it is better enough to show a harsh face in the conversation too as it is quite natural. And if the person who likes us will understand and reply even for that like how our mother does daily.
Script writers who are writing a variety of scripts for movies, short movies and for stage shows have gathered huge lot of experiences out of their life and by observing things around them and by watching many movies or by reading many dialogue oriented novels would have gathered information from them. It might be easy to read and see a movie but the hard work for imagining a conversation and for writing a set of dialogue by thinking how a character will think and react about this dialogue and how he/she responds back would be much difficult.
Dialogues in live or in screen have much difficulty and the words are much powerful either it is joke or it is an advice or it is an information everything matters through our single response. Making our words pleasant always and not showing our anger then and there and showing it in a right place is utmost way of conveying our thoughts and deeds.
