I’ll try the answer ?? ????? ?????.
Do your friends know who you are? Yes (unfortunately)
Do you? Not necessarily.
Do you even know your screen name? No, I’m impersonating myself.
Maybe it’s just a coincidence that you logged in. Right on the button. I wasn’t meaning to go to my computer. I sat down to it by coincidence, turned it on by coincidence and logged on by coincidence
