I think the last time I kept a diary was over 20 years ago. I think I still have that diary somewhere in my piles of books. There aren't any very personal or intimate posts anymore because I tore those pages away. I certainly do not want to die suddenly and left behind a tell tale biography.
When I was keeping a diary, I do write some very emotional stuffs and etc. In fact, I love keeping a diary so much and will keep a lot of ink pens of various colours to go with my mood on that day.
Now, that we have the new medium call blogs, I guess no one ever keeps a diary anymore.
