Oh wow you unlocked a deep memory of mine. As a kid I could drink milk so I had some leftover in my bowl and some leftover orange juice in my glass. I mixed them in the bowl and the acid curdled the milk and it turned all flakey and I felt like a scientist unlocking some kind of mystery.

Also, yeah, that's not weird. I like fresh fruit in my cereal. People buy cereal with dehydrated fruit in it. Fruit juice is just an extension of that. You've cut out a middle man.
