volunteer hours

Today,I have finished my ten hours of volunteer.Iworked at Pro Built MachineryCORP.
Through working at this international trading machinery CORP. ,I learned a lot of things such as how to write invoice make different graphs.
My first day at this company was doing basic work.I typed the invoice for the manager and made calls to different trading companies for further information on their products such as the price and size pf the products.It was not easy at first especially talking and working with a lot of people I do not know.Also,I had to work as an adult which seemed to be very challanging to me.
More than that,the other comnpanies that I called seemed to wonder why a "child"was making phone calls to them to ask information about their products.I had to explain again and again and I was fustrated .
My second day was much smoother.I was not as nervous as the first day there and finished my work more effciently.I did not have to make so many phone calls and copy down so many prices and details which I was relived of.The manager was quite content with my work and agrees to sign my certificate for me.
Through working at a new place,I learned how to be patient,how to be brave,how to get on with others and finish my task on time.It was a challange and also was much fun because I had never worked at a company before and this was my first time to do so.
