Okay, if you want TRUTHFUL stories.............. here ya go, and here I am embarrassing myself, cause it was me who was the silly twit!!!!
Aged 12, end of the first year in Grammar school. and in Biology we had learned about many things, including the reproduction system, AND respiration system (and a lot of other systems in the body. all of us being SOo sure they'd ask us about certain things, the reproduction system in particular, we swotted up like crazy, continuously drawing the diagrams and correctly labelling the darned bits and pieces shown. Got the whole thing down pat, circulation - check, brain - check, reproduction system - check, respiratory system - check. RIGHT, with all facts and figures remembered by rote, we were more than ready!
Sat down the the exam. hah, a cinch, going swimmingly, got to the answer with a system beginning with R...... go no further, thinks I, and proceeded to draw the entire reproductive system, with all diagrams and everything that would have been expected. I was SOOOoo proud of myself. Wasnt till I got outside, when we debriefed about the exam at lunch break, my friends pointed out, no the R wasnt for the reproductive, but respiratory system. ummmmmmmm.......................... failed the exam!!!!!! and I was SOOOOOOO embarrassed!! couldn't look the biology teacher in the eye for a few lessons after!!!!!
