“cats on hot bricks could take hints from me”

“A brick could be put on the end of a scale, to determine if the other end of the scale holds a lie or the truth. (Hint: The truth is much heavier than a brick.)
”

“Wait,  Cat,”  I  say,  reaching blindly for her arm, as if I could possibly make this anymore awkward. (Hint: apparently, I can.)”

“A brick could be used to ascertain the truth. And then logically, a non-brick could be used to detect the lie. What kind of things are non-bricks? Well, anything from blankets to lies. So therefore, a lie could be used to detect a lie, and all this logic makes me want to grab a blanket and lie down—and that’s the truth.

“If a cat sits on a hot stove, that cat won't sit on a hot stove again. That cat won't sit on a cold stove either. That cat just don't like stoves.”

“A brick could be used to remind me of her. I mean everything else reminds me of her, so why not a brick too?
