Thanks for your reply :) If it was possible, I would have avoided the situation entirely as I genuinely didn't know what kind of feedback to give, but I now know I should have just avoided that particular point and just said something about the slides or something similar. To be honest, I can imagine very well as I'm a bit autistic myself, but my parents handled my autism absolutely terribly. I think this caused my view on these type of things to be a bit skewed, so thanks for setting it straight. :)
