I made a boo-boo today

I knew it was going to happen eventually. Last period of the day, I became naturally very thirsty, and what did I do? Crack open my Pepsi while the entire class was reading. Man, I've never seen so many heads turn in my life by hearing that "SSSSSSSSSTT" sound as you open a pop. And, what's worse, I took a chug before I realized what I was doing. Of course, I had to apologize profusely, etc etc etc. Talk about embarrassing, holy shit.
