What was happening to me this morning was so unbelivable! I walked down the street while a woman stopped in front of me and asked me for directions to the nearest bank. At that moment, I was seeing my friend Bui across the street, I called out to him and asked him to wait for me. Luckily for me, he did. Bui saw everything while I talking to the woman, a pickpocket was put his hand into my backpack. Bui started to walk away. I thought he didn’t want t wait for me, but I was wrong. When Bui saw the pickpocket he went to call the police. They were arriving immediately. The police arrested the woman and the pickpocket. What an experience..
