"And of course we'll need to stop by quills and sofas again to get more quills..."
"Uh huh."
"And after that we'll stop by the mayor's office to fill out that paperwork, that should take maybe twenty minutes if everything works out how I expect it to."
"Yeah. Okay."
"Spike? Are you even listening to me?"
"Sure. Whatever you want, Twilight."
"SPIKE!"
"GAAH! What?" Spike yelled in surprise, dropping several boxes of scrolls and books he was carrying.
"Were you listening to a word I said?" Twilight glared at him as he struggled to pick everything back up.
"I was trying to, honest! Its just... this is a lot of stuff and I can't carry it all and listen at the same time, its impossible!" Spike balanced a few boxes as he reached for a scroll on the ground. He lost control of them and they went toppling down again. Spike groaned and continued to pick things up.
"Why didn't you say so?" Twilight rolled her eyes. Several boxes were engulfed in purple light and floated into the air. "If it was too much for you, you should have said something."
"I tried, but you were so caught up in your plans that you ignored me."
"Did I?" Twilight looked shocked. "Oh, I'm sorry Spike, you know how I get sometimes. How about I handle this and you take a break. I'll meet you back at the library for an hour." She turned away and began walking.
"Really Twilight? You mean it?"
"Of course I do. You are my number one assistant, after all, not my beast of burden." She chuckled and turned back to face Spike, but he was already gone. Twilight watched a trail of dust heading toward Rarity's boutique slowly settle to the ground.
"Beast of Burden..." Twilight rubbed her chin. "I'm sure there's a spell for that. Maybe something similar to a familiar." She shrugged and began walking to complete her errands.
