I kept asking myself, why do I hate him so much up to the point that I managed to throw his gifts, delete his pictures, remove him from my YM list, scrap his SMSes, and even unsubscribe all the online networking portal associated with him?  -- The things that I did not manage to do with my ex's stuffs.

I think I finally got the answer.

Because I used to think that knowing him is the best thing that ever happened in my life.

Stupid me.

Yes, I regretted knowing him.
