My Mommy sometimes takes me to a big room with lots of people in it. Usually one or just a few people are standing in front of everyone talking or singing or jumping around. When they finish, everyone in the room slaps their hands together. Mommy grabs my hands and puts them together, saying "Yaaaaaaay!" I usually smile, because it's really kind of fun. Last night I realized that I could put my hands together all by myself and have quite a good time doing it. Now whenever Mommy or Daddy say "Yay!" to me, I get excited and start clapping.
