Whenever we go to our friend Hillary's house she goes straight to the kitchen. And anytime she sees Hillary go into the kitchen, she follows her in hopes that she'll get something out of it.
She grunts, and points, and climbs, and begs.
I have to admit, its hard to say "no".
And after she's communicated what she wants and knows she's getting it. She gets really excited and knows the rules. She goes to the kid's table and sits down politely.
Then after eating a few bites she'll usually find some adult, bring her snack to them to show them what she has...gleaming with pride.
