Like Michelle mentioned, I think passwords are a strange example because a lot of companies and schools require you to constantly change your passwords often and they eventually go from sentimental to practical. Maybe that’s a metaphor for how our letters/long, heartfelt emails have transformed into practical, transaction-based messages.

I do like your point about remember the face. That’s one of Reddit’s official rules is to “remember the human” and I think is often forgotten about even on sites like Facebook where we know what the people we interact with look like and usually have met them.
