So, I've seen people do this trick where they make it look liek you said something, liek this happened with a friend:
<Me> No!
<Friend> Yuuuus
<"Me"> Okay, okay, you did.
<Friend> You admitted it!
<Me> No I did not. That was an evil witch taking over my chat for a moment.
<Friend> Nupe.
And I asked her hwo to do it, but she said that she wouldn't tell me. So, how do you do it?
