My male colleague sent me home. I said I got off, and he said I got off. What do you mean?

The male colleague kindly sent you home. He may think that you will thank him or have something to say to him. Maybe you appreciate him and ask him to go home and do it. But I didn't expect you to just say get off and leave like this. He may be a little frustrated, maybe a little dissatisfied, and think that you don't pay much attention to it. He, driving home, had nothing to say and some intentions. May be a little reluctant to leave.
