Playing at the Park "Not Yet"

There's a community park a couple blocks away from our home. When I got home from work, Alan and grandma was waiting for me outside. So I decided to take Alan to the park. He had a good time and he plays along with other kids. When there were just the two of us left in the park, I asked him if he wants go home and his answered was "Not Yet!" I been hearing that words a lot from him lately. When his shoe fell off and I put it back, I asked him to say thank you and again his answered was "Not Yet"

Here's a short video of Alan playing at the park.
