1. My childhood dream was to become an actress. I used to like watching old films with my parents. I have not still achieved my dream but maybe one day I will.
2. I used to watch old films, used to like skating and playing with my cats. We had 2 cats, but now we don't.
3. I think that hobbies and activities change because we get older. In my childhood, I used to think that 50 rubles is a great sum but now I understand that it is not. I used to like lots of sweets but now I prefer meat. Life is changing and we are changing too.
