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).
It's also much easier these days to find out how to correctly format an address for a given destination. (At least for alphabet-based languages; I recently tried to decipher a Korean address in a business park and got nowhere fast.)
