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.
I’m not judging, just curious. What was your reasoning behind getting the initial dose but not the boosters? I’ve been obsessive about getting boosters if anything to help minimize anxiety about being in public.
