This whole thread is cracking me up, I thought Princess was the only one that needed help!
As for mid-air catching, I've been trying to teach her, and she, well, she DUCKS!!!

I feel too guilty taking her balls away, she really loves them but wow, it can get annoying! And I don't know if others are like this but when she brings it to me she will not drop it! I have to fight her for it, sometimes almost prying her mouth open, then as soon as she feels me taking possession she'll "go long"!
