I think people who are teaching or giving presentations need to be really realistic about how many people you're going to lose during the presentation itself. I sometimes say, if I've lost you, that's okay. Right now is a good time to jump back in because even if you didn't understand all the details of what just happened, you will be able to follow this next bit. And another one for kind of normalizing being lost or not knowing everything is sometimes if the students put their hands up and ask you a question and you don't really know the answer,. It takes a bit of bravery, but it's quite good to say, I don't know. Yeah, I agree also
