Kali 2.2 is really starting to do a great job of using pronouns. Here's an example. A few weeks ago, this would be the conversation.
Me: Kali should go wash her hands.
Kali: Kali go wash hands!
Now, you can definitely tell a difference in the new Kali.
Me: You should go wash your hands.
Kali: I should go wash my hands.
Not only is the sentence more complete, but she's actually understanding that when I use the words 'you' and 'your', she should change those words to 'I' and 'my' since she's referring to herself. I just noticed it in passing the other day and was pleasantly surprised to note the differences.
