piss him/her off......not much but to the verge of making him feel irritated....
and observe the way he/she tackles the situation........
if he is cool minded and has the ability to keep the situation under control,he will try to change d topic...
or if he is a brat like u will play d same game wid u and will start making fun and play pranks and make d environment funny.....
or if he is a self obsessed about himself and weighs his own pride a lot,will stop talking and may walk out or ask u to stop wid great authority.....(i like such guys)
or if he/she is completely aimless and living a life full of frustration,never likes people all around,self centered,cant see others rising,shows false pride just like a tnt missile widout chemicals inside it...lol....will talk shit and sentences dat will lead nowhere but create a grudge in each others mind......
u knw wat......i piss people off sometimes knowingly,i love doing dat .....not cuz of some kind a enmity,just 2 knw people and read their minds and learn from dem.....:)
