Translation of holgazanería

Thank you for writting back so quickly. I learned English when I was a kid, because we've always been in England during summer vacation, since my grandma used to live there when she was still alive.
Sorry, I did not know that I have a meeting with a friend. I will talk about our trip. Many thanks for the email and I hope we write eachother again soon and next time longer letters, I promise.
I now live in Spain. I have moved too 2 years ago. I have finished my studies and in February I'm going to high school. I have not spoken German for a long time, actually since I was a kid.
