You Know When?

I picked the kids up from school on a day that they had all attended an after school class.  Owen is taking a comic book drawing class, and Lilly and Sam are taking sign language.

Sam said, "Lilly was lying on the ground during class."

"Lilly, why were you lying on the ground?"

"Because, like, my heart hurt, you know?"

"Lilly." Owen says, with scorn and derision.  Everything Owen says to Lilly if full of scorn and derision. "Do you mean your CHEST hurt?"

"Yeah," she replies.  "My chest and lungs."

Sam pipes up, which is, in itself, somewhat unusual, because he is so OVER "kid" conversation.  He told me the other day that he just didn't really find Owen and Lilly very interesting.  That, sure, he was "technically" still a kid, but what did that even mean, really?

It means you are 11, dude.  Chill out.

So it was notable that he was choosing to engage in this conversation.

"Oh, I know exactly what you mean Lilly.  Like when you eat too much protein?"

Huh?

"Oh, yeah, totally," They all chorus in agreement.

"Or, like, too much applesauce?" Sam continues.

"Exactly," they respond.

Soooooo.  Is this a thing?  A protein and applesauce related heart attack?  That happens to everybody else but me?
