Love at first sight is an emotional conition 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 or crush, but 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 an intimate relationship with that person. 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 (such as in a crowded place). Sometimes two people experience this phenomenon towards each other at the same time, usually when their eyes meet. See also love.
