Do you prefer working after office hours?

In principle I do not support and like to work after office hours. Official jobs are to be finished within the stipulated time frame. But, at the same time I do like to have any pending important works in my hands. So, working after office hours should not be a common phenomenon or practice in life, it may be occasional, if required. Because there are other things to do after office hours as we need to lead a decent social and family life.
