First notebook entry: Introducing myself

Hi!
I'm learning English, because I want to study in Ireland. It is my dream, and dreams have to come true =) I would like to find more information about education in Dublin or in others (other in this case means plural as it is so there is no need to add s) Ireland's cities.

My native language is Russian. If you want to know anything about Russia, i I will be (don't forget to add the verb "TO BE") glad to help you.
(There are not bears on our streets =))

My hobby is reading. I like Hugo's novels. And I also like Russian authors for example Bulgakov or Nikolay Ostrovsky.
Besides that (you indicate that you do something else other than the hobby thing you listen before) I play the flute. Early Earlier in life i I wanted to be a musician. But but (there is no need to start a new sentence when you can continue this one) now I don't.
