how do you finger out if gals are angry always??? 
anyway, i am tempted to say that girls are actually born vicious
and abominable. just to scare guys off, but well, this is AA, so i
shall give my sincerest comments.
if your gal keeps "getting angry", it may just mean you're (i'm
sorry to say this, but no ofence ok dude?) thick. you don't get her
SIGNALs, and keeps saying things that she don't wanna hear, or dun
say the things she wanna hear.. thats why she's pek cek with you
lah...
on the other hand, if you see she's always angry with other people,
not you only, it may just mean she's really born vicious and
abominable. in which case, get yourself a couple of beers, and a
new gal.
