My daughter had her first sleepover and it was with a family that originated in India. They had spaghetti for breakfast. The idea that only certain foods are acceptable for breakfast is silly, and considering the bizarre history of cereal it's nice to see cereal in decline.

Edit: Regarding questioning tradition and rules- I remember reading a book called "Indians of the Oaks" and feeling pretty validated that the traditional diet of the aboriginal people of the San Diego region only had 2 meals a day, and they managed just fine.
