this one not classified under sensitive liao.
this one is classified under despo 

and because of despo, came the sensitivity, and worst, for most,
when they cannot get the gal they wanted, they turn around and
critise the gal, me kenna many times by guys liao, even in
Sgforum here, they can pm me and said sweet stuffs to me, praise my
beauti, jam up my mails, then i told them politely that i am not
interested, they turn around and "F" me and call me bitches and
beaches, all kind of nonsense, very childish indeed.
I dun blame them if they are boys with kid mentality, but most
are adults, and some are Uncles liao, but still never grown up, in
psychology, i learn that is call neotent psychology, indicating a
person who had grown old but still having a child brain. I think
many guys in Singapore had that kind of brain, sgforum is a live
example.
