What do you do?

Picture it... you're a teacher in the middle of teaching a Math lesson... and a nine-year-old girl lets one... yeah, you know what I mean. And it's not one of those quiet ones. It's not even one of those short, loud ones. It's one of those really long trumpet-sounding ones. That alone causes complete havoc in the group as you struggle to keep a straight face; however, it doesn't end there. Just a second or two later follows this smell that could put a university student off finishing his Guiness. I'm talking the raunchiest stank that ever has and ever will exist. Being the responsible, mature teacher that you are, you tell the children to ignore the smell and concentrate on their work. Well, that proves to be absolutely impossible. It was sooo bad that I actually had to step out of the room. How terrible am I? I leave the kids in the room to deal with the smell and I step out into the hall to get my breath back. Teacher's are the most hypocritical people. You've gotta love it. :)
