My little worry wort

So the other day Braxton and I came out of Target and he asked about the smoke that he was seeing. I told him that Burger King cooked their hamburgers over a fire and then he got the funniest look on his face. He started saying "Oh but mom the hot smoke and this cold winter air will make a tornado." Those are his words, honest. He wasn't in a panic but almost ready to see one spin into destruction not far from where we parked the truck. Turns out that about two weeks ago after watching some TV program, dad explained what happens when cold and warm fronts come together...TORNADOES.
