KARACHI - The Valentine's Day is being observed all over the world today. The sensation to mark the day is heightened in City as elsewhere in the country, given the threats by extremists to sabotage the celebrations. Valentine's Day is being celebrated as day to express love and affection for their loved-ones. This year there have been threats by banned organisations, which have warned the public against celebrating the day. Consequently the security in Karachi, Islamabad and Lahore has particularly been beefed up. It has been observed that during last few years the trend to mark the Valentine's Day is in vogue especially among youth. The youth could been seen buying cards, gifts and flowers for the occasion in great numbers. This year the super stores in the metropolitan have also offered different packages to their customers for a week-long period. "We have good business during this period. People have shown interest in buying gifts and other accessories for the event. Whether it's good to celebrate the day or not, we only know that we are making money during the whole week", said a shopkeeper. "The sale-out of cards and flowers has increased. People form all the age groups, especially the young generation; have showed great interest in buying the stuff," another shopkeeper told The Nation. "This is an alarming situation for us. Our younger generation is indulging more and more in such vain activities like this Valentine's Day fever which are contrary to our traditions and we should discourage it," opined an elderly lady. "This day is celebrated in order to show your love for someone special, so how can it be a taboo, a girl buying a card wondered. "In this fast moving world, we have little time to express our love for each other and if there is a special day for it, there is no harm in celebrating it", a boy maintained. "This concept is wrong that the day can only be celebrated to express love for one's mate. Love is not something limited to be brought down to such narrow a notion, one can express one's love to one's family, neighbours, colleagues and all," he observed. "This is ridiculous to confine the expression of love down to a special day. Love is for all seasons and why we blindly follow a western tradition in this regard, when there are more constructive ones we never ever bothered to adopt", a man in his 40s opined. "At Christmas eve, all over the western world clothing and other household stuff becomes cheaper and here in Pakistan, during Ramadan and Eid season these things become almost inaccessible to the general public," he added.
