using preposition to make sentences definite. Is it fine?
Hi! I was doing an exercise and came across the following sentence: When the(1) car behind me gets too close to my rear bumper, I get angry.
So I assumed that the definiteness here is due to the preposition ''behind me''
Similarly '' I don’t always watch the road in front of me carefully enough.''
So we can take THE even when it's not clearly stated which road, just any road in front of me.
Using the rule which I learned I have to use THE in the second example. Not just any people but only those who are around them:
''Harry was knocked off his feet, and Hedwig’s cage bounced onto the shiny floor, and she rolled away, shrieking indignantly; people (2) all around them stared and a guard nearby yelled.''
Why does the word 'people' have no article?
