Caliente

So I have this habit of filling the bathtub with water that is not as cool as it should be... mostly because I turn the water on & walk away to do other things while it fills up.  So the kiddies have gotten in to the habit of checking the water before getting in.  The other day, they dipped their toes in the water & Kyra said, "Oh, caliente." 

Editor's Note:  Caliente means "warm" in Spanish although I've likely not spelled it correctly here.
