Love

What is love ? is it something we felt , something we see , something we smell or something we hear ? can we love a dead object like sand or rocks ? How do we know when we have felt this love ? have you heard of love at the first sight ? is love only to opposite gender ? according to http://www.answers.com/topic/love ."Love is A deep, tender, ineffable feeling of affection and solicitude toward a person, such as that arising from kinship, recognition of attractive qualities, or a sense of underlying oneness. A feeling of intense desire and attraction toward a person with whom one is disposed to make a pair; the emotion of sex and romance." In my opinion , love is something that you could do to God , Friends , your couple , your pet's and even you pensil.Is there something you can't love ? of course you can't love everything in the world , you must have some like and dislike , if we can love everything than whats the purpose and meaning of love in this world????
