Once upon a time, some decades ago in Bear Country lived two bears. Actually, quite a lot of bears live there, that's how it got that name, but we're talking about two bears in particular here. They had a son that they named Nail who they loved very much. A few years later they wanted a daughter. So some months after... another son, named Sickle.
The two bear parents (bearents?) loved their two sons, but they really wanted a daughter, so again... they failed. They had a third child who they named Hammer.
The five bears lived a happy, peaceful, uneventful life, doing all the usual things. But one day, Sickle came to an important realization. Sickle wasn't sure what to do about this, and felt like crying. And that's when Hammer passed by. "Sickle," asked Hammer, "why do you look like you just saw your friend get hit by a truck?" Sickle turned away. "Go away, Hammer. Don't look at me."
