unhappy

It's a boring afternoon.I was asked to attend a meeting which is about  food.Ninety percent of the big names in the food industry are here.And I feel embarrassed.The prefessor who shared it with us was really good.But i can't understand he,first of all,I can't understand his accent and secondly i can't understand what he said.Therefore,the whole process of sharing was suffering for me.I'm just a student,and i can't participate in the discussion of the big names in the  industry.So i think i am asked to fill the number.It waseted a lot of my time.I could have done a lot of homework all afternoon.
