I'll get out of my house, and start to walk straight ahead. When I'll see the second street I'll turn right and in the next street I'll turn right adn when I'll see a wall I'll stop and turn to right; in the next street I'll turn left and in the next turn right. The post office is located there.









Look at the map. Imagine you're at home and you want to go to the post office. Which way should you go?
