One of mine didn't recognize a busy signal, asked what the sound was. I thought he was kidding.
Hmm, I will put my hand up for that one. When I started a new job twenty years ago, I had never used a fax until that time even though they had been around for ages. Every morning I would send stuff through to head office and sometimes would also need to use the phone. Since the phone and the fax both ran off the same line, all I could ever hear was this weird sound. There was never anyone else around to explain it to me, and it took ages for the penny to drop. Not adapting to technology is supposed to be an old people thing, so I was already showing the first signs of aging in my thirties. OMG, I have never told this to anyone before and if you all laugh at me I will scream.
Reception is poor where I live these days. The phone company sometimes rings to sell stuff but don’t believe me when I inform them that there is no reliable signal. Apparently the entire country has proper service, except for my house and my neighbours’ house (they need to walk 200 metres up the hill to make a call, with an especially weak signal when it rains. LOL they are older than I am, I imagine them holding a mobile with one hand and an umbrella with the other). For me it’s really bad during strong wind, so I too have to go for a walk up the hill. Oddly enough, it’s harder to hear a phone call when there is a gale blowing directly into your ear. Most of my friends don’t even bother answering their phones when they are visiting because calls get terminated as often as not before messages are full understood. But yeah, the phone company insists on peddling their version of the truth. Oh, and because landlines are a thing of the past, they are falling into disrepair. Oddly, the phone reps who receive complaints deny this, but enough of the technicians who visit your house are a bit sick of living the lie and just tell it like it is (off the record, of course).
