I don't think it's really a question of grammar. It's more a question of usage, or style.Originally Posted by barbieantonis
How do you tell somebody he is annoying you? It depends on how polite you want to be.
1) Stop that!
2) Please stop doing that. It annoys me.
3) Would you please stop doing that? It's very distracting.
As you can see, there is a variety of ways to say the same thing (as usual).
