But I do know that of youre talking to someone, and look him in the face, and say to it "Yesterday you were saying : boris Johnson is a w#nker and only cares for the rich." your "you" really is the person you are talking to.
For a start, I'm not looking at anyone in the face when posting on the internet.
I know your life is only the internet, but that is not the case for everyone.
Then, let me give you another english lesson:
I am talking to someone in person and looking at them in the face.
This someone hasn't got a driving licence and never driven any vehicle.
They say: "it is perfectly ok to pass a red light if nobody is coming from the other sides"
I reply: "YOU can't pass a red light, even if the junction is clear"
YOU in this case doesn't mean YOU personally, the person I'm talking to, because they don't drive.
It is intended that nobody can pass a red light.
In your queen's English it might be incorrect (it's not) but real people use this form of language.
You need to get out of your hole and meet real people.
Believe it or not, there are other human beings out there, with legs, arms and head attached to their body.
They communicate without a keyboard, by the magic power of speech.
Now, this is the last English lesson I give you for free.
Follow my advice, go out.
