Love at first sight is an emotional condition whereby a person feels romantic attraction for a stranger on the first encounter with the stranger. The term may be used to refer to a mere sexual attraction, crush, or even an object. However, it usually refers to actually falling in love with someone literally the very first time one sees him or her, along with the deep desire to have intimate relationship with that person. This usually happens when the object of his, or her love, for instance satisfies his subconscious concepts of beauty. The stranger may or may not be aware that the other person has any such notion, and may not even be aware of the other person's presence. Sometimes two people experience this phenomenon towards each other at the same time, usually when their eyes meet.
