By the time dinner started, they were gone. That may change in time. We still have plenty of time. They were already walking in pairs. Actually, he had been studying for a while. As far as I know, it wasn’t the first time either. The plan was good in terms of time and transportation. He could do it part-time. He was hungry from the time we left. He’d come in from time to time. I thought so, too. After the seminar, there’s time for questions. They walked together as if time had not passed. They stopped because of the time. It all depends on the time of your arrival. I am a regular fan of his music.
