My brothers' name are Hector Miguel, Daniel Clemente, Jairo Enrique, German Demetrio, and Nestor Emilio. My sisters' name are Ana Lizzy, Dilma Patricia, Claudia Virginia, and Diana Marcela. All of these are longer names. The name of my younger brother was different. When my parents chose his name, they thought that the baby would be a girl because at that time we were five boys and four girls.
Some people change their names when they become an adult.
I think that choosing a name is difficult because nobody knows if that name will be good for who will have it. If the person loves the name, it will be good. If it is bad, the problem will be big.
