groups? assignments?

here's how things work in a group. if i belong to a group, then i should contribute something, at least something, to the group. ok well, i've attended a group meeting, and it didn't went well for me. it was like, hey, you're a stranger here. they really gave me this barrier feeling (if anyone knows how it feels) i spent 5 hours straight, from around 4pm until around 9pm in a totally different place, totally different surroundings, and totally different people! and worst of all, i sat there for hours, not able to do anything. they asked me to do stuff, but i couldn't! it's like wth is assembly language? i have no idea how to program a calculator! and another thing is the group members..which..erm..i don't know at all, were talking bout 8 bits calculator? or 16 bits? and what if 8bits * 8 bits? it would be 16bits, and where to store the extra 8bits in the microcontroller? and how to retreive the 8bits which isn't in the accumulator?!?!? wth?!?!? if i can answer those, i won't be taking that course! if i know that well i'll be able to produce tonnes of calculators myself! and imagine being told off jokingly to participate more in the group. what am i supposed to do? blurt out lame jokes just to participate? talk crap? well i'm not that kind of person. prefer to look stupid rather than being someone i am not!
 
and an hour ago, the group i'm supposed to be in, told me that they were going to see the lecturer. and he didn't tell me what am i supposed to do, to follow him? or was he just stating a statement, informing me that he'll be meeting the lecturer? for the kind of people i am, i followed his back to the lecturer's room, even though i don't know what i was supposed to do. he actually saw me before entering his room, but didn't signal me to go over or to stay put. i decided to stay out, coz i don't really know what he is up to...to tell the lecturer that i'm not participating perhaps? anyway, i waited, and he went off, and i went off too! i don't think he knew i was waiting, and he didn't saw me when he got out. well, for me, it's like ok, i've done what i can, but i can't do much. i just don't know where, how and when to contribute!
 
if any of you do watch malaysian idol, i feel just like that fella who sang eidelwise and go the distance, the guy with trembling nose. he didn't fail to get in the top 30 because he can't sing, but i feel it was because he couldn't mix around well. i feel just like him, or he being like me. anyway, that's how i would describe my situation now.
