> I never understood why people care to keep their private conversation history in the first place.
One reason that's understandable without relying sentimentality, is they're a record of what you were doing or thinking at a particular time, much like a private diary.
There's been a few times where I've gone back though stuff like chat history to better understand something that I didn't realize the significance of at the time.
I never was disciplined enough to keep a diary when I was younger, but I started using messenger when I was about 14. It’s pretty amazing to be able to go back and see my interactions, the way I communicated, the way I saw the world (am now 30). I feel lucky to be able to have that window into my past life.
