They do not, however, belong in my work email in-box and instant messages. I say this, because I work with several remote employees fairly regularly. There is one, in particular, (we'll call her Petunia) that I honestly have no idea if she hates me, loves me, thinks I'm the stupidest person on the planet, or hails me as a genius, because of her less than predictable use of emoticons. She is an over-winker, for sure. It follows instructions, greetings, scoldings...I'm not sure if she wants to date me or thinks I'm an idiot. Sometimes I want to ask her if her computer has something in its eye. I can overlook a friendly smiley or confused face in the office, but if the end message looks like my 2nd grade daughter wrote your email with a box of crayons because of your emoticon use, you might consider cutting back a bit.
Kick the Smiley Habit...
