re Ian Parkin's caller being selective.
One of the oddest I've received was selective by sex rather than age:
I had answered the call itself as I usually do: just "Hello?"
"Is that Mrs. Graham?" a man with a British accent asked.
"No, I'm Mr. Gra.." Click! He rang off so fast I barely finished my name. Err, do I sound female on the phone?
Goodness why he wanted my wife not me, or what he wanted to ask / sell. Still, he'd proved he didn't know my marital status.
(A status at least making the Domestic Management's permission to bake a 4"-scale steam-wagon's steel tyres at Regulo 9 for 30 minutes to shrink-fit them, readily obtainable!)
I turned the tables once on a YL with an Asian accent, trying to sell me a 'phone contract. The initial caller had been male, but clearly unable to convince me a monthly £8 contract was cheaper than my £5 max / month PAYG rate, had transferred to her, hoping she'd sweet-talk me into complying.
I soon moved the conversation away from phone contracts, and "Angel" and I enjoyed not just that first but two more very pleasurable, social conversations, one a week, all at her firms' expense. Then it stopped. I hope they'd not twigged our game and had fired her.
