Come in, Go in
Another teacher and I have recently discussing two topics on which we disagree. I'd like you to express your opinions about them in order to clarify our conflict.
What is the exact difference?
When do you say one or the other?
Can it be used in singular without an or the in front of it?
If so, please give an example.
Thank you all!
It depends on which side of the door you are on. If you are inside, use 'come' and 'go' for when you are outside the place.
Some other person did it.
