Anybody notice any interesting behavior from their Miis? Forgive me if this has been discussed or is obvious, but I've been sitting in the Mii plaza while surfing and just realized that my Miis occasionally chat with each other and one of them even sneezed! No mingling or parades yet....just got my first friend...so I may be a little behind the ball here. So I hope this isn't a repeat. Just curious what you guys have noticed.
