A thief getting access to my room

Something happened when I was studying last night. I would have an examination the next day so I studied until eleven. I was too sleepy that I could not pay attention at all. Therefore, I lied on my bed to have a rest. But at the moment I slept in my bed, some noise woke me up. The noise was from the window. I walked there and opened the window to see what was happening. Oh! I saw a man who was climbing up the pipe. He tried to get my neighbour’s kitchen. I was so afraid that I hid myself behind the bed. He was a thief! Luckily, he knew he was discovered by people so he ran away quickly. Now, I always remind people to lock all windows and doors before they go out.
