Can I say?
1 If something that moves so fast that it disappears before I can see what make it was. So can I say:
- That was a man / woman, wasn't it?
- That was a child, wasn't it?
- That was a doctor, wasn't it?
- That was a professional footballer, wasn't it?
2 If I don't know how is a chef, and then there is a person who came into a room, cooking a meal and then left/exited. So can I say after pointing to the door or in the direction of the person, that has gone by, "That was a chef, wasn't it?"
