Different emotions such as (")(-_-)("), are expressed by changing the character representing the eyes, for example ' T ' can be used to express crying or sadness (T_T). The emphasis on the eyes is reflected in the common usage of emoticons that use only the eyes, e.g. ^^. Looks of stress are represented by the likes of (x_x) while (-_-;) is a generic emote for nervousness, the semicolon indicating sweat that occurs during anxiety. Repeating the /// mark (///) can indicate embarrassment by symbolizing blushing. Characters like hyphens or periods can replace the underscore; the period is often used for a smaller, "cuter" mouth or to represent a nose, e.g. (^.^). Alternatively, the mouth/nose can be left out entirely, e.g. (^^). The parentheses also can often be replaced with braces, e.g. {^_^}. Many times, the parentheses are left out completely, e.g. ^^, >.<, o_O, O.O, <.<;, though this is more likely in Western culture. A quotation mark ", apostrophe ', or semicolon ; can be added to the emoticon to imply apprehension or embarrassment, in the same way that a sweat drop is used in anime.
