A short letter for an editor Sorry for the delay in responding. When I received your email I was on the island of Tenerife where I did not have frequent Internet access. Now I have returned to England, which has allowed me to write to you calmly. We are grateful to your response on the article and also the hard work of all the reviewers. It has been a beautiful experience, although it is a pity that this time our work can not be published in your collection. We look forward to offering you our contributions to the possible future cooperation with you. Sincerely, Ana
