I am of the mind that it helps keep track of history for one. Secondly, it lets you peek inside someone else’s inner thoughts and emotions so that you can have an experience you wouldn’t otherwise have (just as you might when you read a book). Maybe, in this age of isolation from tech and now, Covid, getting access to someone’s life through their journaling is your first taste of intimacy. I believe to be human, is to be intimate, and deep, and to bring connections we might not otherwise have. So, ultimately, it lets you connect in a personal and deep way and that is something that is rare to find these days.
