There are so many ways to improve your English, and most of them are fun to do. For example, you can start watching series or films in English, with subtitles in your language at first but then you can change it to subtitles in English until you don't need subtitles at all. Another great way, is listening to music in English while reading the lyrics so you learn to identify words and also get more vacabulary. But I think the best way to improve your vocabulary and grammar is reading books in English.

Over three weeks ago, my grandparents found a beautiful brown and white dog (the veterinary said it was a Beagle). It was just a puppy, we guess it was about six months old and its owners left it on the streets. My grandmother fell in love with it as soon as she saw it, but she was convinced that it was lost and went around the neighborhood, asking everybody if any of them had lost the beautiful dog in the past few days. She didn´t get an answer. Just one person said there were three more dogs, like the one she had found, in this neighborhood since two days ago. My grandmother brought it to her home and talked with my grandfather, they decided to addopt the dog, they named it "Danger".
After two or three days after finding it, my mom and uncle met Danger, they played with it and decided that, since it was a strong and lively animal, it couldn't stay with my grandparents anymore (they thought that it was dangerous walking and playing with Danger, because it could push my grandparents and hurt them, a 76 years old couple). Since that moment, they began searching a new family for Danger and they finally found one.
Today, a friend of us picked up the dog and took it to a new house. While the dog was getting in the car my grandmother was crying. Perhaps it was the best for everyone, but it was also difficult for them.
I can't stop thinking about being old. If they had been younger no one could've decided anything for them. I suppose that when they were children they were always thinking about being adults, making their own decisions and being completely independent. But now, I think they feel like children, letting their daughters take decitions for them. I'm thinking which moment is the deadline, when we just leave our adulthood and become children again.
