Context 1: Let's say me and my friend are in my moving car, and there is a car behind us; and I think that car is following us. Can I say either,
"The car behind us is following us"
"The car behind is following us"
I am sure we can say, "The car behind us is following us." How about, "The car behind is following us"? Do you think it is okay?
Context 2: Let's say I am walking with my friend on a street.I suddenly stumbled, and my friend asked what had happened. Can I say these interchangeably,
"A guy behind pushed me"
"A guy behind me pushed me"
Again, I know we can say "A guy behind me pushed me"; but I wonder if we can say, "A guy behind push me."
