Email is still really useful when you have a lot to say but don’t want to write a letter. If I’m catching up on the last several weeks with my parents, I’m not going to write a 10-page text. I can write a nicely formatted email and attach a few photos, though. It’s far more convenient than writing a letter and stuffing a bunch of printed photos into an envelope.
That’s a good point. I guess if I’m in the situation where I have a lot to say; I’d rather just talk on the phone with someone. Now that I think of it, I feel like the telephone replaced physical letters before email even came along. But, I do highly respect the long-form communication of letters and email. It’s just kind of rare these days.
