Freezing Cold Weather and Frosty's

So, I pick up Morgan from school this afternoon and as soon as she gets into the car she asks me, "Mom......can we stop by Culver's for some frozen custard"? I, of course, swung around and said "Girl, are you crazy it is freezing outside"! And I left it at that.
So what do I do? I pull into the Wendy's and order her a chocolate frosty and myself a vanilla frosty! I HAVE GOT TO BE OUT OF MY MIND! Sure was good though....... :)
