1.My Dad took a photo of me standing next to Robbie Williams!
2Then Dad suggested to go to the British Museum. 3We decided to go there by underground. 4The station was very crowded, and soon I noticed my little sister wasn't with us. 5We saw her when the doors of the train closed — she was still on the platform! 6We went back. 7We were looking for her everywhere till someone told us that she had been taken to a police station. 8We rushed there and found her chatting happily to a policewoman. 9We were so relieved!
10After that we didn't go to London for a long time. 11And when my birthday came, Mum and Dad took us to Alton Towers instead. 12Oh, Alton Towers!13 It's a wonderful theme park with lots of great rides!14 This time there were no disasters. 15It's true, we spent over an hour waiting to get on the new rollercoaster, 'AIR'. 16As soon as the ride which lasted only for about two minutes finished, we joined the back of the queue again. It was fantastic!
17My parents wonder why I enjoy rollercoaster rides and I can't understand why they like going to those boring museums. 18But I've got an idea about our family trips. 19Though things sometimes go wrong, the main thing is that we live over the situation doing things together.
20These days trips are the experience of spending time wjth the family — ' the time we are going to talk and laugh about remembering our disasters as real adventures.
