Be Positive Miss Fabrianti

I want to tell you one person who could i say "she is quit annoying" in my new office.. i dont wanna being negative shit about people around me. i am just trying to know about different people and different behavior.. i am not saying she is bad person , but i am just feel she is Unwelcome to me.. she felt her job was taken by me, whereas i didint do anything.. She's always trying to "teach" me how to do things that I clearly already know how to do ( i mean, technically i know but yes i need a lit guide from who have experienced) but it does not mean she can be cynical to me, she can underestimate me.. its unfair, he should tell me where her task that should not be done by me. so that i know what is my job and what is not mine.  to make you easy to read this story , maybe for the next couple hour we can call her miss sinistis hehee...because she never smile on me, she just smile with the one she known better..  i give you one case, so that you know if you are in my position. Last week Our team is meeting to discusss about organized to our event were held next month. members of the meeting are head of our division, member of database support, my second bos, our customer service, staff of membership, miss sinistis and the last one is me.. we talked about the preparations, the invitations, the decorations, the consumptions and the last is about printing.. usually all about printing are hendle by miss sinistis because she have subscriptions vendor to provide what she need to print, but special for this event my boss go forward by him self to handle these printing stuff. he isnt tell miss sinistis about that.. but when my boss have a little difficulty to bargain price for printing, he asked miss sinistis to contact the Vendor.. but miss Sinistis do not want to contact the vendor because she felt she isnt the one who bergain the price for the beginning, so she did not want to be blamed if the price is inflated to the cost of printing. she want the first person who negotiations with the vendor who should be responsible, and without confirmation and saying any word she pointed to me to be responsible.. I was surprised because I did not know anything about these printing problems, why she blamed me about that ? at that moment I was immediately denied.. i said " i dont know anything, i didint do anything.. i dont even know What materials will be printed... " then she believed and she ask my boss about that, and my boss said he did by him self and want to miss sinistis to help him.. and then she realize that i do not involved even a bit about her job.. you see.. during this time she felt I was taking over her job thats why she never being friendly with me.. but i feel greatful because i have learned to become aware about type of my co-worker.. the important thing about all of this is would be nice if  not to judge anyone because mind your own business...  i am trying to recpect her all the time, because i believe when i be nice to her, she will do good to me in return..
