Translation of refrenar

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.
Choosing the right language school is not an easy task. If you want to learn Spanish for example, you first need to know which country you should visit, because the pronunciation in each country differs.
I would be pleased if we can still keep the contact alive. In the future I will have more time to write emails in Spanish. At the moment I just can't. Sorry for being so direct but this is the truth.
