It's how we roll.

::Last year when they were threatening terrible ice storms, (which never came, by the way,) and Mama and I were in town::

Mama: "Well, do we have everything we need if we get iced in?"

Me: "Let me think. Do we have milk?"

Mama: "I don't know why everyone automatically thinks of milk at times like these. We don't even drink milk!"

Me: "You're right. Do we have plenty of Dr. Pepper?"
