You can also add an emoticon to your message.
The more complex an emoticon gets, the less effective it is, because the image becomes diluted.
Whether you choose a quote or an emoticon, take a few seconds to type and brighten someone's day.
The inclusion of a happy face or another form of smiley or emoticon helps to show immediately whether a comment is meant as a joke or in a light hearted way and is a great use of netiquette.
Another aspect of instant message smileys is the indication of other facial characteristics - for example, the comma representing the tear in the last emoticon above.
