I called my dad a professional worrier. Many in his family are also professional worriers. I sort of inherited this talent - I don't think quite to the same extent though. Or at least over time I believe I have become less professional in my worry. Nevertheless, daddy worried that I worried too much and a few months ago wrote me an email that said: "I know that telling you not worry is like telling a bear not to shit in the woods."
Words of wisdom.
Thanks for the eloquence, dad.
