Mmmm. [She finishes up her hair and places a finger to her lips. It's a good question.] Well. It's not about how much the seashell is worth to me. It's about what it's worth to you. Some shell you just found probably doesn't mean a whole lot. It's a nice memory or maybe it's petty. It's something you can easily give away. That's how I feel about my knowledge. I have an abundance of it and I'd like to give it away. I just can't... Thus a seashell is a good trade because it's something we can both easily part with.

And you can do a lot with a seashell. All sorts of magicks and what have you. It's not useless and neither is my advice. That all balances out, you see!
