For example, I see some of them in my university; the professors arrive at university at about 7am (working hours start at 8.45am) and sometimes go home at 7pm or 8pm (working hours end at 5.30pm). We must also bear in mind that most of them do not live in the city but rather in other cities that are an hour or two away from their work. I feel that they don’t have any social life, and that their homes are like graves where all they do is sleep.
