****************************************
It is not really up to you to prove that you are not cheating; it would be up to your accuser to offer evidence that you are. If there is no such evidence, then there is no valid reason to accuse you. If there is evidence that you are cheating, at that point you can explain what has really happened and why it might appear that you are cheating even though you are not. Sometimes, there are ambiguous social situations which can be interpretted in more than one way.
