Well, as for me , I like to ride a bike, ( in summer) and skating in winter. These are my hobbies.
My friend has got some hobbies too. He likes rollerbladig , besides he likes to play chess in his spare time. In winter he prefers to go skiing.
Yes, we've got a common interest. In summer we sometimes like rollerblading together in the park. It's rather exciting.
I would say, no. We are chatting by the phone a couple times in a week. It takes us no more than 1 hour. He is busy and I have got a lot of things to do.
Well, there are lots of them nowadays. It's difficult to say about the most popular.. I guess, travelling and firney are the most popular ones. People want to see different countries and to stay in a good shape. That's my opinion.
