@victorgijsbers I am neurospicy and can't follow a talk without e.g. solving nonograms or sudokus. It's sad that everyone things that is disrespectful but I live with that. Additionally, not every talk of a session might be interesting, but instead of walking in and out during sessions, having people to stand up and creating noise, I maybe read through one talk. What I actually find rude is people talking in the audience or typing really loud, i.e. creating a distraction for others.
