Not sure if it's being exaggerated for comedic purposes but it is interesting to me how alien the act of sending a letter by post is to the author. Granted I don't send them very often but I wouldn't think much of it if I had to. But I guess younger people and particularly those in tech may genuinely never need a reason to send a letter (or, it seems, write an address by hand).
The stamps I have, I bought years ago - by now, they don't cover current letter prices. I wind up putting too much postage on the letters, because I'm not going to go buy even more stamps that I probably won't need...
