Hi to everyone, I'm new here and I have a silly question and I hope that you can help me with it.
I know you do or I know you know.
If I'm talking to someone in a conversation, and he or she tells me "I know", and I quickly reply to him or her "I know you do", would that be gramatically correct?
I don't know if I should say that or something like "I know you know".
Maybe the last option sounds a little bit weird?
Thanks in advance, guys.
