plunged into accounting

I'm here earlier than I planned. I was offered a job for two weeks, I refused at first, but then.. tempted by the money I was promised and by the chance itself to get some experience in interpreting right at the beginning of my "career", I agreed, talked to my grandma, got her consent and exchanged the ticket. So, today was my first day at this company. Next time I will not focus on particular terms but will ask for a general explanation of what is going on. Because the first, say, three hours today was, as D. says, "pain and humiliation". My interpreting skills and knowledge seemed like a very subtle advantage. Everyone (but me, of course) had an idea of what was being discussed, while I was groping for the right words. I felt like a blind person who's been asked to lead a group of more or less healthy people. They didn't mock at me or something... but there were these condescending smiles and looks on their faces when I said something in a hesitating voice - like, "oh, look at her, poor girl, she doesn't know a thing in our field". Anyway, after a few hours of trying and listening, I finally got some image and timorrow, I'll show them who is who.
