Last holiday, I went to Surabaya with my friend for vacation. We went there on a night bus. When we arrived in Lamongan, the bus stopped at a small restaurant for a rest. I got off the bus to get a cup of ginger tea, and my friend drank some cold lemonade. Then I went to the toilet. It took only a few minutes. When I came out again, the bus was not there. it had gone! My friend was not there too. Feeling shocked and confused, I asked a waitress about the bus. She said that the bus departed about five minutes ago. I tried to call my friend on my cell-phone, but the battery was running low. I could not do anything but hope and pray. After several minutes, my wish came true. The bus came back. I got on the bus and walked to my seat. I was so ashamed when everybody on the bus looked at me. I could feel my face turn red. What is the topic of the text above?
