Why he has not realized that he was process-oriented programming

Give yourself a reminder, always thought with the object-oriented language, with the encapsulation, inheritance, polymorphism, with a design pattern, that is, the object-oriented. Then, by chance he recalled thinking at his own writing code, emmm. . I seem to have been the class as a container with ah, the longer the program did not class as an object, but has become a container that contains functions to achieve. Although written may be consistent with object-oriented rule, but mentally and process-oriented.
