Its true that one has to draw a line somewhere saying that beyond this anything is indecent. But a kiss can't cetainly be that line. If one is parting with his beloved, say in a railway station, a kiss is something which comes very naturally. They can't go about searching for a place where there won't be anyone. I frankly don't think the law makers have to be told of all these things. They know very well what is permissible. Its been a story for sometime now that a section of the society (some people who unfortunately are in authority) are bent upon forcing their own opinion on others. They need to be told quite strongly that they have to take a consensus before making any rule that deals with common people.
