Do you think I'm nosey for watching a couple argue?
That depends. Why were you watching them?
I don't know but they were boring. I thought they looked weak.
It can make other people feel bad to have people watch what they are doing. It might seem like you are spying on them.
It's not my fault if a couple stars arguing in front of everyone.
They shouldn't have started to argue in public because that does attract attention but it can make you look weird to be watching some people argue. Other people might think you are nosy.
