Keeping a notebook

I like Didion, have tried to keep a notebook or diary, but for one reason or another have not kept up on it. I recall being maybe 12 years old, and my grandma gave me my first diary that you had to have a key to open and I remember her saying " no matter what kind of day you have or who is unpleasant towards you or if you are just upset with your parents, you can always tell someone your deepest, darkest, happiest or saddest secrets that no one can see, and that's this diary." Those words have stuck with me, even now that I am a mother myself. I remember keeping up with my diary even a few years after that, writing down everything that I could possibly think of. But now that I think about it maybe it was or is a little obsessive compulsive, or even dumb, but in a way i think we all long to keep a journal of some sort, to hold on to the small things that we feel will some day be lost, either due to age or whether we are just running out of room in our minds to store them, because it has filled up with everyday life like grocery lists or bills that are due or birthday parties that your kids are invited too. In one way or another we all write down little notes or reminders if you will that help get us through our lives. Now that i am older I find myself only keeping a notebook when I am really angry and frustrated. I wonder what that means?
