I started using smileys excessively when I started posting on forums.
Originally I did it so people who didn't know me would know when I was
joking around or wasn't being serious. It seemed like many times
people would misunderstand what I was saying without a smiley, and
I didn't want to make enemies over some stupid misunderstanding.
It has since become a habit, but whenever I email messages to people I
avoid using smileys. For some reason emails to me seem more "official".
I admit to being tempted to change to the opposite as a grandparent, just to psych the young 'uns.
There's something very entertaining thinking of you doing this.
