Probably not too kindly. Still, Fuu was optimistic about being able to make friendly contact with the unicorn, and about its intelligence--she wasn't an expert on unicorn lore, but it was hard to picture one as an unintelligent creature.

She stepped forward, waving politely. "Excuse me, Lady Unicorn!" (Might as well go all the way with the formality.) "Would it be all right if we said hello?"
