We've all been there, we're in some public place (in my case, a chemistry lecture hall of nearly 200) and something entertaining/mildly exciting/etc. happens. Most people simply acknowledge it, process the niftiness of it all in their mind and then go about their day. But there is always someone who must shout some over exaggerated, "WOOOOOOOOOOOO!" from the back of the room. To all of you over exaggerated responders, this rant is for you...
Listen up. We get it, you have limited self esteem and therefore must define yourself by drawing attention to yourself. But might I offer a suggestion, do so discreetly. Shouting, "WOOOOOOOOOOO!" from the back of the room (where you have been sitting talking to your friends for the entire lecture. Seriously, just stay home so the rest of us can hear the professor) does not make us turn to you and think, "Wow, he must be a totally awesome dude because he really knows how to emphasis the exclamation point at the end of his utterance." Instead we think, "Seriously, this guy is that impressed by a floating soda can? Just wait until we get to make foaming volcanoes for the science fair...oh wait, we did that in the second grade. Maybe he should go back a few grades."
I admit, science lectures a fun. Balloons explode, cathode ray tube electrons bend with the application of a metal, and diet soda cans float while their regular counterparts sink. This is truly exciting stuff (no, really, have you ever sat in on a psychology lecture? Comparatively speaking, science lectures are WAY better) but each demonstration does not require an over exaggerated (and forced, might I add) response from you. Learn to internalize this tendency to shout every minute reaction that you feel. Trust me, your classmates will thank you for it.
