I have a family. I love all my family, mother, father and sister. Family for me - it`s a very important thing. And all family members getting an influence on me.

I like to do many interesting things with my family. We have different hobbies, but do many activities together. We playing computer games, watching TV, listening to music.

If you want to have such a happy family, as me, you should love all your relatives. Don`t swear with them, and follow their interests.

I want to ask British people, how do they keep their families always happy and what should I do in order not to upset my family?
