Unfortunately I can’t revisit this with my mum as she has now passed on.....I can only really put the acceptance of the conversation as being partially due to confirmation bias where one side at least was expecting the regular call to discuss family matters and went with it with the mind subconsciously choosing to discount the minor detail of the voice sounding different!
I’ve done it myself where I was expecting a call at work from a pal of mine and when the call came in I started giving him all kinds of abuse (because as young idiots that’s what we did on our calls!) This good tempered but rather brutal abuse went on for a good long while until I finally twigged that the banter wasn’t being reciprocated....only then was there a sizeable pause and the caller said “...........I don’t know who you think you’re talking to but that person isn’t me” I had quite merrily slagged off a rather senior officer.....I felt this horrible all over chill go over me and I went into some kind of auto-babble apology. Fortunately he took it all in good humour otherwise I would never have made it to Corporal Girth, nevermind Sgt Girth.
My squaddie son often answered his phone with 'Yes sir!' as if he were still on Guardroom duty.
Probably a good habit to get into.
On recognising voices: back when the ex and I first
went on the phone as it was known then, I was home alone with the baby one day when I had a series of obscene calls. This bloke was looking forward to doing
all sorts with me.
As I wasn't used to talking on phones I didn't recognise the voice, although it seemed to be some acquaintance as he mentioned things like family names that a stranger wouldn't know.
There was no caller display or 1471 yet so I couldn't get the number. Phones were wired in so you couldn't unplug them. Leaving the phone off the hook made it play a whining tone after a while, and anyway I needed it working.
When I hung up it rang again, over and over, so I couldn't even ring the operator for advice.
I took it as a creepy prank rather than anything dangerous. No-one who knew me that well would expect me to be intimidated.
When the then Mr Snail came home I told him and he answered it, and slammed it down after hearing what Mr Caller would like to do to him too.
After that we left it off the hook covered with a pillow to damp the noise until next day, and it never happened again.
We never told anyone. No point, nothing could be done, and I knew I'd find out who it was one day.
At least ten years later, chatting with an ex who'd been away from the area for that long, I suddenly recognised his voice as the Creepy Caller's.
I pointed at him and said 'You rang my husband and offered to suck his big dick!'
Bloke's face was a picture. It was him.
