Since it happened so long ago (in "early 2009", more than nine years ago, right?), she can simply say that she honestly can't remember what she said back then, right?The fact is she said SOMEONE is acting like a slut today and she has to tell the judge WHO is the someone if she is not referring to me. And based on WHAT she said that. I am not worried of proving it at all.
And since you are accusing her this year (in 2018) of "sexual harassment", based on only a few words that YOU can only remember her saying over nine years ago and with neither witnesses nor video recordings to support you, do you seriously think the Judge will agree with you?
