when I was in college I worked as a waiter.  and when I entered the university, I devoted time only to study.  After graduating from university with honors, I became an accountant in a prestigious company.  to this day I am the chief accountant of the company.  Yesterday we had a corporate evening ended on a cheerful note.  And today I was invited to a party but I can't go, I have a lot of work I have to finish my presentation by tomorrow.
