'I don't know what's happened to my best friend, Sarah. I'm quite worried about her. She used to would be a really fun-loving person but she's changed. It all started when she would go to Africa after college and worked in a village, helping poor children. She used to be there for two years. She obviously loved it there, but she's become really serious. She never use to be like that. When we were at college together, we would go out in the evenings - to the cinema, to cafés and so on, we weren't use to worry about anything. We would often go away at the weekend with a group of friends and Sarah used be ready to try anything - horse-riding, ng, sailing, surfing - all that. But now she prefers to stay at home because she thinks we shouldn't spend money on these things. She is never used to criticise me so much - now she says that I need to take life more seriously. She used to tell me the other day that I was wasting my life! I know that she's learnt a lot from her work in Africa and that she's right in some ways, but you
still need to have some fun, don't you?'
