The bear is going to the post office. He points to the map and asks Micky, “Excuse me, how can I get to the post office?”

Micky tells him, “Go straight ahead. When you see a red building, turn right. Go along the road. You must turn right when you see a green building.”

And then, Mcky says,” You should go straight until you see a yellow house. Then you should turn right. The post office is just there.”

The bear begin to look for the post office. He turns right and goes straight. And he turns right again. At last, he turns right for a third time.

The bear meets Micky again, “Why have you come back?” Micky asks.

What's wrong?
