Please correct my text.

Hi. My name is Alexander. I am from Russian Federation. I should tell you about my hobby, but I should also say, that this is not an easy thing to speak about it.

There are many different hobbies in the world. I watched on the 
internet a little video-clip about a man's hobbies recently.

Anna from Moskow's hobbies are dance and playing the piano. From time to time, she does ballroom dance. It is beautiful.

Tom from New York has a hobby of reading books. He likes russian literature. For example, he likes the novel Anna Karenina or the long novel War and Peace. It's a way of spending time and a recreation from work.

Alice from USA has many hobby like dance and sports, for example cycling. She loves to help homeless in Centre for Social Assistance.

Now i'd like to tell about my family and about their hobbies.
I have a mother, a father, and a grandmother.
My mother is Marina Vladimirovna . Her main activity is work in the periodical press. When she is free, she is fond of playing chess. It is her hobby. 

My Father is Sergey Vitalyevich. He is a creative person. He paints pictures for the gallery of the city Kursk. It's both work and a hobby for him. 

My grandmother is Elena Nikolayevna. She is pensioner. We are in the middle of winter now, therefore she has much free time. She think what have a hobbie too (I don't know what you're trying to say here). She is fond of gardening. Gardening is one of the oldest hobbies. She grows flowers, especially roses. Also she lives with us and helps my mother to run the house and she is fond of knitting.

I think, that i should talk about my hobbies. I have many hobbies too.
Like other people, i love listen to music. Sometimes i make music with the help of a computer program. Usually It's electronic music, in trance style.

I have one more hobby. Speaking. It's language exchange. I'm studying english language on site of internet. The adress is "http://www.italki.com/". I need help in learning english. And I get it. Sometimes i help people in learning Russian.



I suppose, that's all I wanted to tell you about hobbies.
