Steel or Feathers?
"Hey, Poppy," Rika said, patting the girl on the head, "can you tell ol' Rika what's heavier: a kilogram of steel, or a kilogram of feathers?"
"Oh, the steel, of course!" Poppy replied eagerly.
"Kiddo, they're both a kilogram."
Poppy blinked. "But...steel's heavier than feathers?"
Rika grinned and shook her head. "Here, let me show you."
Soon, there was a scale set up on the desk in the main room of the League building. On one side, there was a small block of steel, and on the other, there was a large bag of feathers. The two pans were completely balanced with each other, much to Poppy's obvious confusion.
"But...but that's cheating! That one's bigger," she protested, pointing and waving at the bag of feathers. Then, she turned and shouted, "Grandpa Hassel! Steel's heavier than feathers, right?"
Before he could reply, Larry cut in and said, "Actually, feathers are heavier, because you have to live with the weight of what you did to those poor birds."
Poppy was silent for a few seconds as she processed this information. Then, she proceeded to latch onto Rika's leg and start sobbing about "Those poor birdies!" Rika sighed heavily as she tried to comfort the poor child, and Larry ignored the glare she briefly shot over Poppy's head.
"Larry, please," Hassel whispered, closing his eyes and rubbing his forehead.
"What?" he said defensively.
In hindsight, maybe that hadn't been the best example to use in front of a Flying-Type specialist...
