I wouldn't cast magic around them. They can get spooked pretty easily. And besides, if you lose and take a chore from me, so long as it's done completely and satisfactorily, it wouldn't matter to me how it gets there.

It's not that I can't bet money. It's that I don't care to. It makes betting more complicated, but not impossible.

Isn't there some pesky little task you'd rather pass off onto someone else if you win a wager like this?
