What is love?

If i put this question in an open forum.....i am sure i would be able to create a riff between people just like our political parties.... but if i am asked to reply the same question i would rather say. Its the most beautiful thing to happen to Anyone. Lots of people are very much cyyanical about love. Some say it as LOss of valuable energy and all sorts of Acronyms and Synonyms will come up. Also people have categorized love into several forms,just as a Sceintist keeps on discovering something and keeps on Giving the same species different genus Name...but for me love is a simple one word definition of your inner feelings and joy that you feel. Be it for your Parents, your motherland, the most palatable food...etc etc...I would rather term those persons hypocrite who say they have not yet fallen in Love. Let me put down a simple question to them. Dont u love your mother for God Sake? if yes then why cant you bring the same feeling when it comes to some other forms of love. Also i would say i would find a lot of people or rather i have come across lots of people who say i love this and that but when it comes to deeds they are not sure wether they can do or not.
When i refer about Romantic love. Love for someone special, i myself cannot describe what it is....Its not only about liking the other person but also caring and respecting his thoughts his actions... its very easy to say i love you but truly very difficult to maintain it. Falling in love is awfully simple, but falling out of love is simply awful. I could fill a thousand pages telling what is love. how do you know its love but i just wanted to know what other people think about love hence i have posted this topic, to see how people feel about love. I would request everyone to please pen down their thoughts as well.
