Ditzy Burnette?

For most of my life, I've been called ditsy, dumb blond, etc (I had natural blond hair until I got pregnant).  I am book smart, but there are times when I have lacked in common sense.  I try hard to overcome this stereotype, but....there are days, like Monday when I proved people right yet again.

I wrote yesterday about how I butchered a recipe and served raw chicken.  This is a recipe that the lady in my carpool lady gave me. 
Specifically, she said:
put chicken in a 9x13 pan.  Add one cup of cream of chicken soup and 1 cup of milk.  Then, in a separate bowl, mix stovetop and 1 stick of melted butter.  Put this mixture on top of the chicken and bake on 350 for 30 minutes. 

I followed these directions to a T.  When it was a big fat failure, I was stunned. 

So, yesterday, on the car ride home, I asked what I did wrong.  I repeated her directions back step by step.  Well, apparently, you are supposed to "cook" the chicken first.  Seriously...would you all have known that?  Am I the only one who assumed the chicken would cook itself in the oven?  Please tell me I'm not alone here.
