i got a colleague who suddendly give me cold shoulder earlier
part of this year (around March 09).
now she's pretty much ignoring my existence, don't talk to me
during lunch, no eye-contact, nothing etc. Go home take same lift,
i tried making small talk with her casually but she only give nods
and 1-word reply.
However, when she needs my help, she suddendly smile very
sweetly and cutely.
this is what pisses me off.
i think she's like this cos' i always tease her a bit, but i
think like that she also cannot. 
anyway, in such cases, what will u folks do?
1) ignore her and treat she doesn't exist
2) be casual and take it as if nothing happened, and smile and
greet her whenever u meet at corridor etc., even though she don't
even look at you
these few months, i've been doing 2) because this is what
gentlemen do, but i'm starting to question myself if this is what i
should be doing.
1) seems to be very petty and calculating, u know......and i'm a
guy.
she ignore me is no big-deal, but i just find it very insulting
that she can change face and smile so nicely when asking for my
help. It's like, she comes to me only when she needs help.
i've no problems with other female colleagues, btw, and we get
along well.
and no trolling pls. this is a serious thread which i'm seeking
opinions.
thanks!
I think the reason of your frustrations is because she failed
to behave according to your expectations?
You probably expects to be appreciated by her after helping her
on many occasions and you are upset because she doesn't give you
the coy reaction and behave a little bit more open and
comfortable towards you even after you have helped her many
times.
Things can go very wrong and uncomfortable between you and her
even if she had a nightmare about you out of the sudden. And there
is really no way she is going to let you know and also for you to
find out what exactly happened. As we're very emotional type of
people, you can only accept it the way it is...that is, she woke up
one day and suddenly felt very uncomfortable towards you.
You should help her ONLY if you are comfortable
with providing that help or else it is better for
you not extend your helping hand towards her.
An alternative method is to buy your way back into her good
graces by buying her flowers extensively over a period of
time...maybe 1 to 2 weeks?
Reason for doing that? Let her know you are trying your best to
RESCUE the person who has offended her. (The reason why her
reaction is super bad towards you)
