Seems there is a shortage of homes, hotels, restaurants, parks or night clubs in Delhi. Couples have now taken their PUBLIC DISPLAY of AFFECTION to Delhi metro too. I am no conservative or narrow-minded person but at times excess display of your love in public places makes others uneasy. Everyday I see so many couples during my metro ride getting intimate with each other, hugging, touching, and feeling each other in full public view of fellow metro travelers. There is nothing wrong in PDA but it definitely gets the unwanted attention from lechers.
