A smiley is a sequence of characters on your computer keyboard. If you don't see it, try tilting your head to the left -- the colon represents the eyes, the dash represents the nose and the right parenthesis represents the mouth. Smileys usually follow after the punctuation (or in place of the punctuation) at the end of a sentence. A smiley tells someone what you really mean when you make an offhand remark. They are also called emoticons because they intend to convey emotion!
