My grandmother kept a diary for years and faithfully wrote entries every single day. I received a diary when I was 11 (birthday present, I'm guessing) and made a rather half-hearted attempt to keep a record of my life. Unfortunately, I wasn't very good at it, and I had a younger brother who kept stealing it to read it (even though there was very little written inside -- go figure).
I did make some notes about life with my new adoptive "family" during my first couple years there. I'm transcribing them now just as I wrote them then.
