Stressful lunch yet learn a lot

Today is my second week of so called attachment. Lunch with bosses as usual, stressful but full of experience. I've less work to do now, but my six sense told me that my master did not plan to bother me for this moment. I dunno whether I'm too sensitive or thinking too much or whether my six sense is true, I felt my master treat me differently after I've submitted by work to him. Is he not satisfy my work or thinking that I'm worst of the worst that wasting his time and material in his firm? I couldnt explain why, I cant speak or answer a very basic question posted by them properly. Even it was just a single question of do u like or dislike sth. I'm so stress when togather with them who were those senior professionals. I felt I'm just like a garbage among them. Asking me which book of which author, which subject of which principle, Fifa world cup etc with most of my answer of I DUNNO....what the fuck pupil I am? Knowing nth, I believe I'm a young ppl who is living dull life to them coz I dunno n hv no intrested in so many things. What is my problem? I think I need to list them down and find way to curb it, as there must be a way out am I right?
