What unusual or cool hobbies do you have?

Wendy45

I like to design transport maps. I always draw them because I don’t like painting very much. At weekends I go on the bus or train. I go to see new stations and bus stops. I remember them and when I get home I draw them. Sometimes when I visit a town, the transport isn’t very good. Then I create new maps for those towns. A lot of people think it’s a strange hobby but often other people are interested. I chat with them online about my hobby and I put my designs on the Internet. I think people sometimes use them when they visit the towns.

Cyberboy

I’m in a dinner club. We are all teenagers and we meet for dinner every week. We don’t go out to restaurants for dinner – we cook the food and eat it at home. Twelve people are in the club and we eat in a different house every Thursday. We surf the Internet for ideas then we buy the food after school on Thursday afternoon. We don’t go to the supermarket because the food isn’t very fresh. We always go to the local market.
