all the very best
develop your own "departure message". don't just say "goodbye". craft a neat sentence and use it always. make it your hallmark.
Here are a few examples to get you started:
* Be seeing you
* All the very best
* Toodle pip
* Missing you already
Find one that fits and wear it out some. Let me know what you come up with.
I'm much obliged to you for posting this.
i always say 'have fun!'
