Line of control

The conversations n communications can be done on any topic ranging from a seed to sky scrapers,mythology to science,etc.there lies to limit for the same.But we humans' always have only particular topics to discuss wid ceratin people.Like to illustrate a dad n son,would tongue on education,politics,motivation,sports n stuffs.Have u ever heard them speaking about adult stuffs.its obviously impossible.there comes the line of control on tongue which we sketch.while wid frendz we speak on films,the scenes,censors,n many current date issues.
the conversations definitely has to be well done with lots of issues discussed.this firstly polishes the speakers verbal skills,lights out information to both listener n the spectators.
the speech shud surely be done in a real smart manner ,the line of control which makes its picture.thus Line of control though invisible (heheh) does exists to put a limit to the things we tongue on....
