Cereal Mixing

Today, we had cereal for breakfast. For Sylvia, Weetabix; for me, Cheerios. 

"Have you ever mixed cereals?" Sylvia asked. 

I recoiled. I'd never imagined such a thing. 

"Mixed cereals? Like, two different kinds of cereal in the same bowl?" 

"Yeah," she said. "It's the cereal power move." 

I said "Blech," or words to that effect. 

Before today, I've never heard of people mixing breakfast cereal together. Do other folks out there actually do this? If so, what cereals do you mix? 

I suppose combining, say, Special K with Corn Flakes wouldn't be so bad.
