my 12 students, all of them older than I was. I   2   hard to remain clam in class and   3   they wouldn't
find out how unconfident I felt most of the time. I was quite   4  , actually, until the end of   5   and the
night of the final oral test.
    The test was going to start at 7 pm, and at 6:50, I  16  myself in the teachers bathroom to   17  all the
test questions again. I really wanted to learn the  18  by heart so no one would think I was an inexperienced
tester. The  19  is, I actually locked myself in the bathroom. I  20  couldn't get out! The bell rang at 7 pm
and I could hear the noise in the halls  21  the students went to their rooms. I tried hard to  22  the bathroom
door, but failed.
    I heard the cleaning lady's voice and asked for help as  23  as I could. However, she wasn't exactly a
thoughtful person, and started  24 . "Diana's locked in the bathroom!" Shame had fallen upon me!  25 , the
course director, the secretary and some teachers were outside the bathroom trying to get me out, and,  26 ,
my students gathered outside too, happily saying things like "Aren't we  27 ! No test today!" All I could do
was  28 , and my entire  29  was waiting for me outside, naughty smiles on their faces."  30 ! Teacher."
They said, "We know you are human too!"
     They all passed their test. True to the Brazilian style, we all went out for a beer afterwards, and laughed
the whole thing off.
