worst audience behavior

for me the worst audience behavior is fooling araound with your peers, because i think that if you fool around you will eventually in sometime talk or even get to scream, also you will distract other people and aybe involve them in whats happening. so for me thats the worst  thing you can do in a presentation or in a place.
i think that my behavior was good, it was a really interesting presesntation so i didnt need to talk or distract myself.
maybe i neeed to improve that if some talks to me i say no, whait till later and not respond the.
but i think it was pretty good.
