My friends like to tell me before they fart like it's important. They get really excited, like I wanna know about it. "Jeez I'm gonna fart." "Don't do it in here ya dickhead there's no windows." Or they tell you after they've done it. "I just farted." But nobody ever tell's you while their doing it. That'd be a bit weird going "I'm farting! (Pause) Still goin'!"
