To answer your question at the end: Yes, Indeed have I been to dumb and boring presentations. Now, I'm openly going to admit that that I'm 16 and I know people may think us teens find all presentations boring, but this one boring presentation was about something I really enjoy doing.

It was a presentation in a nearby local center about why young people should get into audio production, DJ-ing and why the should enroll into some sort of DJ Academy in my city. However, the presentation was just sooo boring and poorly structured.

It was so boring that the 'poor' presenter didnt even manage to ask if theres any questions or such before everyone started leaving the moment he stopped talking.

Dont get me wrong lol, I make music myself and I'm heavily into music production so a one would think I'd find it interesting but without structuring and preparing your presentation It's pretty much impossible to enjoy.
