I'd just make things up or keep it fairly surface. You will encounter classes and seminars and workshops semi-regularly that seem to go this way. I've learned to keep it very surface and play the game to just get through these for the grade or the hours,etc. I'm not about to try to explain to virtual strangers my truth, nor will I try to explain to them why I hate these kinds of activities. It just isn't their business in any way, shape, or form. So, I grit my teeth, play nice, make something up or tell a vey surface-level, watered-down version of the truth and just get through it. Not pleasant, but doable.
