I am always alone

When I arrived England I don't know why I don't like talk too much with other people .I really don't have too many best-friends.I think it has two reasons,one of the reason it's my English not very nice, so when I talked with somebody , it is more difficult for me.The other reason will be I am not open. I don't like to go to pub, I don't like to go to skate and I don't like do a lots of things.Some people always call me go to pub or skate.I always say it's too expensive for me and something. In fact I don't like to go, so I said that.I don't know why I am so closure. I just like stay at home and use the Internet all day.So now I'm always alone. Now I just want to get better English and I can understand the lesson on the class and other thing is not importance.
