I've often thought I'd like a waving smiley icon to use when greeting new people in the newbies section because often I just gesture when I meet someone and don't really say much.
But thinking about this more I figured that I could use this as an exercise to do what 'it' doesn't want me to do. So sometimes I jump in and say g'day and sometimes 'it' wins :). In other words, I sometimes use it as a self observation exercise.
I didn't realise that he was waiving.
