Swamped

Brooms. Brooms are everyday, boring things. The sort of thing a curious, troublemaking kid isn't going to go poking around, because brooms are for cleaning.

So you thread a few bristles through the ring, and shove the broom in a corner.

"Finished already?" Barb asks, walking into the stable. "Doesn't look like it. Or is the smell getting to you?"

Oh. Right. You had the broom because you were cleaning.

You're about to explain what you were doing, but all of a sudden, you catch a glimpse of something and it gives you pause about letting her know the full story.
