You still send and receive letters? Somebody sits down, puts pen to paper and writes a letter? Folds it, puts it in an envelope, adds postage, and mails it?
Outside of hokey "Christmas letters" (typed once, printed, and mailed to many), I haven't seen a real letter in many years.
I'd say I envy you, but then someone else would reply and tell me that if I like letters so much I should send one. And I suppose I should, but I know I won't. I'll send an e-mail.
In any case, if I got letters I wouldn't throw them in the trash.
