Aside from the sheer uncomfortable yoga positioning they were forcing us to do on those rock hard carpets, spending so much time on the floor has its other follies. It also turns out that when you spend a lot of time hunched over sitting Indian-style, sprawled out, or bent over on a hard rug...etc., any disturbance or show of force when coming to a stand can cause unintentional and unexpected internal "shifts" (especially true after eating anything they served in the cafeteria). This knowledge comes from personal experience.
It was the 4th grade. I was nine. The floor group thing was over and we were all to go back to sitting in our chairs like people. I forced myself up, and from out of you-know-where (and without even checking with me first), as if just to say "hi!"... out blurped this low and sputter-y "bluRRRp!" It was a fart, not very loud, but just loud enough. I just froze. It was a pure "what was that?" kind of moment, and I didn't even know it was me for a half second. I did a mental damage report. All systems were go. Shorts were go. Awesomeness was definitely go! At least I could be thankful it was deployed from a half stand position because if I had been still firmly planted it probably would've launched me at least an inch into the air! "Houston, we have liftoff." But let's not exaggerate. I'm not taking Apollo 13-style liftoff, I'm talking more like Apollo 13-style explosion. "Houston, we have a problem..."
I wouldn't have thought much about it from there, but these two girls (who didn't like me much already) were sitting just a few feet behind me, and I tell you they had front row seats to that performance, both forced to weather the storm I'd just unleashed. One quickly remarked to the other, "ugh, Mark just farted." Now I didn't know if I should've been ashamed or extremely pleased, but I got to admit that one minute of embarrassment for 16 years of "ah! gotcha!" pride is pretty good in my book though, even though it's always more of a deal breaker than an ice breaker. And so I say, "hehe, got ya, girls!"
