In Which My Son Wants Me To Read His Journal

I am so confused by my son.  When I was a kid, I always kept a journal, and it was of utmost importance to me that my mother never read it.  This was so important to me, in fact, that I went to all kinds of trouble to ensure she never read it.  I hid it in my closet, and she found it.  I hid it in a drawer underneath a bunch of other stuff, and she found it.  She would say little things to let me know, without coming right out and saying it, that she had read it, and that she KNEW things.  Things she could not possibly have known, had she not read my journal.  More than once, she said a little something like that, just to let me know, and I grew so afraid and freaked out that she had read my private thoughts, I remember the hairs ACTUALLY standing up on the back of my neck.  I started keeping my journal locked in my locker at school, but then a friend who knew my locker combination went in there and read it.  Eventually I learned that if you really want to keep your private thoughts private, don't write them down.  Anywhere. 
I swore to myself that when I had children, I wouldn't search their rooms for their journals, and even if they had one and left it right out where I could see it, I would not read it. 
But then there's my almost 9-yr old son, Dalton.  He WANTS me to read his journal.  He ASKS me to read it.  His grandparents just sent him a journal with a lock and key on it, so that no one could get in, and he wrote in it, and then promptly brought it before our entire family and had his father, sister and I GUESS what he had written in it, and then told us when we were right or wrong.  I love that he's so open and feels that he can share anything with us.  But then again, sometimes I am absolutely flabbergasted by the things that I read, and the fact that he doesn't have the good sense to know he ought to be at least a little embarrassed.  He writes about a girl at school whom he has nicknamed "Twinklepuff," and how he thinks she likes him because she calls him "MR. Twinklepuff."  He writes about how he rode his bike outside until he "definetely had hypothermia."  He writes all kinds of crazy, funny, sometimes intensely personal things, some of which I won't even quote because even though HE's not embarrassed for everyone to know them, I AM!  I don't know, maybe he's just like me.  I blog about my most embarrassing moments, maybe he's just doing the same thing.  Come to think of it, one day Dalton will discover blogging, and if he hasn't learned to keep a little to himself, one day the whole world will be able to read about whatever rotten and horrible he did that day.  Better yet, one day he'll probably be blogging about ME, old and frail and in a nursing home, and it'll be stuff like "Today, my mom peed all over herself again..."  *Sigh.*
