i strongly believe that we need to have self restriction. Public places should definitely not be misused for physical intimacy. Having said that I strongly feel that public places serve a a very good vent out place particularly in big cities where there are big problem of having private space. And i think kisssing and hugging definitely dont call for a fine. Understood, we are nation of great culture but isnt it true that we are known and admired for our ability to accept others and change with changing times.
