A couple of days, in the morning, Noddy was a little upset and panting. I took him to the lawn for a walk. Normally because people are taking a walk, we don't enter the park.

Since it was already around 9 am, and sun was shining brightly, the lawn was empty.

We went inside. Now there are about more than hundred shrubs there. He started marking them one by one. I didn't discourage him.

Hmmmm, after about 5 mins of frantic marking...He ran out of ummm, ammunition.

Then he tried two three more times and then quitely walked home with me.
