Wow. That was really not our experience in May. Eeyore was the best character interaction at CP. He was being cute (while in character) with the kids by putting their autograph books on his nose and right up to his eyes to sign them (they thought it was hilarious) and pulled his ears up for the picture. He wasn't bouncy flouncy but he was fun fun fun fun fun. That would be sad if he was gone from CP.
And by this argument, Sadness shouldn't be in the park either. But sadness, unhappiness is a real emotion that is necessary sometimes (I watched Inside Out

). I don't think it reflects poorly on Disney or is not what they want to represent at all. In fact, it gives the kids a chance to exhibit empathy. Our kids also enjoyed giving Sadness hugs.
