(Note: blessing, singular.)
There is one, and I'm very thankful for it. Having a head cold means that when your little sister gets sick at four a.m. and you realize that you are going to have to get up and clean up the (ahem) mess that is now spread delightfully all over the bathroom (later you will be deeply grateful that she at least made it to the bathroom, but for now you are not), at least you can't smell anything.
It also causes you to do strange things like sitting up at 4:30 am and eating a cucumber-and-ham sandwich before going back to bed half an hour later.
Oh, yes, and thanks to this lovely affliction, I am considering removing one letter from the blog address/title and calling it:
Inanity Comes Naturally.
Because right now, it does.
Oh.... Poor Anna. :o)
I'll be playing that you get to feeling better quickly.
