Reading Old Journals

Have you ever gone back through your old journals and read them? Or are your journals meant to never see the light of day? I sometimes find some old scribblings and the words are like a stranger to me. I cannot recall what was written. It's odd. Then there are other times when I find an old writing and can almost relive the moment. Which can both be a positive or a negative experience depending on the words written on the page.

So, do you go back and have a good life (or cry) with your former self or are your journal entries not meant for rereading?
