Dear Cold (as in rhinovirus):
Thanks for swinging by. I'm grateful that you came into my life and slowed me down. You reminded me that I need to sleep. That, maybe, I'm working too hard. I got it! I think you've been around long enough...
So feel free to take off, your work is done.
(witness my loving, and anti-histamine-medicated, approach to the stuff that seems like it sucks)
