In cereal, there is two different ways to make it. Pouring the cereal, or the milk first in the bowl. People generally pour in the cereal first. "Pouring the milk first" is considered wrong. People who pour the milk first, shouldn't be trusted.
I had my friend over, and for breakfast he was "pouring the milk first." I will never see him the same way again.
