No thank you please

We had a great day again yesterday. We went to the park in the late afternoon and Kiva was enjoying the sand area. She had her bowl and spoon, I got her a bucket of water to make the sand nice and muddy, and there were other kids there and some extra toys left behind. Kiva was playing with one little boy, a little younger than her but not much. They had occasional difficulties sharing, and his mom and I were working with them. I would tell Kiva to use her words to tell him what she wanted, and his mom made sure he didn't get too pushy. Mostly they got along great. However, at one point he kept insisting on trading his shovel for hers and she did not want to exchange. She was getting pretty mad, so I told her "just tell him no thank you, you don't want to trade". Thereupon, she turned to him and just YELLED "no thank you please" at the top of her lungs. It was just hysterical, and all of the other adults just cracked up. In a few minutes they were playing together quite happily again. She gets points both for politeness and assertiveness all in one episode. [Joan]
