Tempting Fate, and the Seasonal Flu

I totally chickened out of getting a seasonal flu shot today. Weeks ago my employer announced that the company would be offering free flu shots to anyone interested. I dutifully signed up and put the appointment in my Outlook calendar. But this morning, when the reminder popped up I was suddenly gripped with anxiety about the needle, the possibility of pain at the site of injection, migraines, headache, fever, and muscle pain. I just couldn't bring myself to walk down to the room where shots were being given. After all, I haven't had the flu in years. *knock on wood*
