In my country the most common names are: Juan, Pedro, Jordi y Manuel. My family name is common but not the most. My family, usually called me Jose, is my shot name. My name doesn’t mean any other thing but in the case of other Spanish people is very usual to have names with another meanings, and, usually, the people make jokes with them, as: Dolores.
In Spain when you’re working the people use, the fist time, the surname, in my case Campos, is the most common with Mr o Ms.
Usually when you are fall in love, your couple called you darling, or another kind of words, private words to call.
