I used to live in the US back then, and it was cheaper to leave voice messages than text. So, I did. One time I called my sister in Europe, and since she didn’t answer, I left a voice message. She called me back later, pissed off, because she had to call her provider to set up her voice mailbox, because “normal people just text when there’s no answer.” These days, she sends me long voice messages on Whatsapp, which I ignore for weeks at a time. Oh, how the tables have turned…
