How could you do this to me W?

In this post, i would love to pour forth my feeling. The story began when last friday, my bff, A, rang W. She asked her wether she could attend to N's open house on the following day. W said that she couldnt manage to come because she has school programmes. *W is actualy studying in the same school as us. But this year, she moved to a boarding school at setapak, kl. Yes, its not too far from the previous school, but still, she is not studying in the same school we do, anymore! Sobbs :'( * back to the story. Then, ive called A , asking her the same question A asked W *Well, i havent meet W in a while* A told me that W has school programmes to attend. Even if she manage to come, she would be late. Later that night, while i was busy facebooking, i saw W's status popped at the topnews. It says something like this, 'one utama, here i come!' then there was a few comments from one of our junior, P, asking 'W, what time are you going to pick me up? Im so excitded to meet you, blahblahblah!' then, W replied that Y*her new schoolmate* sleepover at hers then the next morning they are going to ou, together! Wtf! Im so sad, devastated and frustrated that she had lied to us. I dont mind if she wants to spent time with Y. But does it really necessary to
lie to us? School prorgamme? At ou? Okay, W, let me make it clear so that you could understand. We've known each other since the firrt day i breathe. So do you really need to lie to us! Hmm. Im frustrated with you, W.
