It's pouring raining outside. I forgot to bring an umbrella.
The streets in Shaw town are not very clear on the map and I am afraid I've got lost.Now I've got soaked and don't know where to go. I ran to the nearest bus stop. I took a shelter under a roof at the front of a department building, waiting for the bus. Luckly, bus came soon. I got on and went home.
