I stare at people in public
Is there a reason you stare at people in public?
No, not at all. I'm a curious person.
It is good to be curious about things. It is rude in American society to stare at other people as a social norm.
Eh, then I'm going to stare at these two studs.
You shouldn't be staring at anyone, really. It's going to make them uncomfortable. It's fine to look a little though.
