I read your comments on this thread and i get you didnt want to say anything and why. I honestly have a simialr midnset to you in this regard when im in similar situations. However, you had the opportunity to tortue her a little. You could have been like "if you only knew how hard it is to physically be unable to say one sentence without being made a fool of yourself" or something dramatic like that. Personally i wouldnt do that but i can imagine a scenario where you could make them feel a fraction of what we have to experience every day.
