When, How and Why have your most strongly held views changed?
Translation: Hllo, my dear. My opinion has changed concerning being well socially. I thought being well meant to have a car, being able to travel whenever I wanted, having friends available, and all those thing melted into ruins as a sand castle. I see things transforming scaringly fast. Everithing is very relative. Whatever is good for me may not be so for you and so on... Well, do you know what I really see? Whatever you do is valuable if a love feeling is present.Nothing else. As easy as water from a river spring, whose mission is to flw into the ocean. Kisses, my dear.
