X: Earwax tastes bitter.
Me: Eww, how would you know?
X: When we were having apples I told Lulu that my apple was bitter and Lulu said that apples are sour, earwax is bitter. So I pulled some out of my ear and tried it.
Me: I see. Do you think Lulu knew that it was bitter because she tried it herself too?
X: I don't know.
