for a minute I blamed the burger that I had eaten at the duty free back in Cancun, but thinking a little further I recalled eating street food the night earlier, as it was Mexican independence day. In the following pages I would like to talk about a topic which should concern everyone of us. It is a delicate topic which has been present as long as human beings have existed and it will last forever. I will start working on it next week. You can also have a look at our site and give me some feedbacks. You know Spanish better than I do. so please be patient with our questions. I would really like to help.
